Abstract:

The Young’s modulus of Ti-Cr-Sn-Zr alloy varies with the composition of Cr, Sn and Zr, in which the elements act as β stabilizers. Some Ti-Cr-Sn-Zr alloys show very low Young’s modulus under 50GPa. The amount of Zr in alloys with very low Young's modulus increases with the decrease of Cr. We investigated the Young’s modulus and deformation behavior of Ti-xCr-Sn-Zr (x=0~1mass%) alloys containing a large amount of Zr. The quenched microstructure of Ti-Cr-Sn-Zr alloys changes from martensitic structure to β single-phase structure if the amounts of β stabilized elements are increased. The Ti-Cr-Sn-Zr alloys with compositions close to the transitional composition of microstructure from martensite to β phase show minimum Young’s modulus. The clear microstructural transition disappears and the minimum Young’s modulus increases if the amount of Cr becomes too small. In Ti-Cr-Sn-Zr alloys containing a large amount of Zr, Young’s modulus depends on β phase that is intermingled with martensite.

Abstract:

Abstract The interface effect on Young’s modulus was investigated in electro-deposited fully-dense Ni –P alloys with a relatively constant phosphorus content (2– 3 wt%), but with different grain sizes ranging from 4 to 29 nm. Essentially the same Young’s modulus was observed for grain sizes ≥ 18 nm. A noticeable decrease in Young’s modulus was found at grain sizes ≤ 17 nm. The reduction in Young’s modulus was found to correlate well with the increase in all interface contributions. These observations agree with various studies on other fully-dense metals for grain sizes between 5 and 80 nm. Previously reported large decreases in the Young’s modulus were likely caused by the significant amount of porosity in the microstructure.

Abstract:

This article presents the results of a study of the properties of epoxy adhesives in an adhesive joint. The study analysed changes in Young’s modulus values as a function of the rigidity of the adhesive and the type of joined material. The values of Young’s modulus values were determined on the thickness of the adhesive joint using the nanoindentation method and in a tensile test of dumbbell shape sample for the adhesive material. The obtained results were analysed in terms of changes to the values of Young’s modulus of the adhesive as a function of the distance from the joined material–adhesive phase boundary and compared to the adhesive material. Zones were distinguished in the layer of the adhesive joint—adjacent to the wall and the core, with different values of Young’s modulus. Conclusions were drawn, indicating the relationship between the adhesive joint thickness and the increase in the value of Young’s modulus. Significant differences were found in the values of Young’s modulus of the adhesive joint compared to Young’s modulus of the adhesive in the form of plastic.

Abstract:

In this paper, two kinds of micro-mechanical models are utilized to predict the effective Young's modulus for hybrid composites including fiber-like, spherical and needle inclusions in an isotropic matrix. The two models of Multi-Phase Mori-Tanaka Model (MP model) and Multi-Step Mori-Tanaka Model (MS model) are proposed by the authors in a series of interrelated research. The results show that the shape and the Young’s modulus of inclusion, aspect ratio of fiber-like inclusion are the controlling factors to influence the Young's modulus, and MP model is more rational to predict the effective Young’s modulus of hybrid composites reinforced with multi-shape inclusions.

Abstract:

The extreme values of Young’s modulus for rhombic (orthorhombic) crystals using the necessary and sufficient conditions for the extremum of the function of two variables are analyzed herein. Seven stationary expressions of Young’s modulus are obtained. For three stationary values of Young’s modulus, simple analytical dependences included in the sufficient conditions for the extremum of the function of two variables are revealed. The numerical values of the stationary and extreme values of Young’s modulus for all rhombic crystals with experimental data on elastic constants from the well-known Landolt-Börnstein reference book are calculated. For three stationary values of Young’s modulus of rhombic crystals, a classification scheme based on two dimensionless parameters is presented. Rhombic crystals ((CH3)3NCH2COO·(CH)2(COOH)2, I, SC(NH2)2, (CH3)3NCH2COO·H3BO3, Cu-14 wt%Al, 3.0wt%Ni, NH4B5O8·4H2O, NH4HC2O4·1/2H2O, C6N2O3H6 and CaSO4) having a large difference between maximum and minimum Young’s modulus values were revealed. The highest Young’s modulus among the rhombic crystals was found to be 478 GPa for a BeAl2O4 crystal. More rigid materials were revealed among tetragonal (PdPb2; maximum Young’s modulus, 684 GPa), hexagonal (graphite; maximum Young’s modulus, 1020 GPa) and cubic (diamond; maximum Young’s modulus, 1207 GPa) crystals. The analytical stationary values of Young’s modulus for tetragonal, hexagonal and cubic crystals are presented as special cases of stationary values for rhombic crystals. It was found that rhombic, tetragonal and cubic crystals that have large differences between their maximum and minimum values of Young’s modulus often have negative minimum values of Poisson’s ratio (auxetics). We use the abbreviated term auxetics instead of partial auxetics, since only the latter were found. No similar relationship between a negative Poisson’s ratio and a large difference between the maximum and minimum values of Young’s modulus was found for hexagonal crystals.

Abstract:

A novel biomedical titanium alloy with the ability to undergo self-adjustment in its Young’s modulus was developed. In spinal fixation devices, the Young’s modulus of the metallic implant rod should be sufficiently high to suppress springback for the surgeon, but should also be sufficiently low to prevent stress shielding for the patient. Therefore, deformation-induced ω phase transformation was introduced into β-type titanium alloys so that the Young’s modulus of only the deformed part would increase during operation, while that of the non-deformed part would remain low. The increase in the Young’s modulus due to cold rolling was investigated for a binary Ti-12Cr alloy (mass%). Microstructural observation and Young’s modulus measurement reveal that the Ti-12Cr alloy undergoes deformation-induced ω phase transformation and exhibits the increase in the Young’s modulus by deformation.

The purpose of the study is to obtain the necessary data for predicting the Young’s modulus of steels and alloys before their full-scale tests. Materials and methods. The data on the Young’s modulus of pure metals and reference data on the Young’s modulus of steels and alloys for high-temperature applications are the materials used in this study. The study uses the concept of "constraint" parameter to rank steels and alloys. Main results. The Young’s moduli of iron and nickel were determined during their operation as a part of steels and alloys, an algorithm for the predictive assessment of the Young’s modulus of steels and alloys was compiled in the temperature range 20–800 °С. Conclusion. It is shown that in the absence of experimental data, the Young’s modulus of steels and alloys can be estimated by the value of the "available" Young’s modulus, determined by the value of the Young’s modulus of pure metals. The results of the study showed the possibility of changing the Young’s modulus of pure metals during their operation as a part of steels and alloys, the characteristics of the Young’s modulus of iron and nickel during their operation as a part of steels and alloys and the algorithm for predicting the Young’s modulus of steels and alloys based on these metals in the temperature range of 20–800 °C were obtained.

Abstract:

We present results from a study of dynamic and static Young’s moduli of North Sea chalk based on laboratory tests on both dry and water-saturated chalk. We obtained static moduli by using both strain gauge and linear voltage displacement transducer (LVDT) measurements. We investigated the influence of pore fluid on static and dynamic Young’s moduli and evaluated the two methods for obtaining static Young’s modulus. We obtained good agreement between dynamic and static Young’s moduli from strain gauge measurements on dry chalk, but for water-saturated chalk the dynamic Young’s modulus was larger than the measured static Young’s modulus. This difference may be caused in part by the influence of the difference in frequencies of static and dynamic measurements. Another reason for the observed difference may be a practical experimental problem that causes the measured static Young’s modulus for water-saturated chalk to be lower than the true modulus. When we compared dynamic Young’s modulus for dry chalk with that for water-saturated chalk, the dry modulus was larger than the water-saturated modulus, probably owing to shear weakening of the chalk. Young’s modulus from LVDT measurements does not relate to dynamic Young’s modulus for dry or water-saturated rock because the LVDT is not able to accurately measure the small deformations of the samples during loading at relatively low stresses.

Abstract:

The field of cardiomyocyte mechanobiology is gaining significant attention, due to accumulating evidence concerning the significant role of cellular mechanical effects on the integrated function of the heart. To date, the protein titin has been demonstrated as a major contributor to the cardiomyocytes Young’s modulus (YM). The microtubular network represents another potential regulator of cardiac mechanics. However, the contribution of microtubules (MTs) to the membrane YM is still understudied and has not been interrogated in the context of myocardial infarction (MI) or mechanical loading and unloading. Using nanoscale mechanoscanning ion conductance microscopy, we demonstrate that MTs contribute to cardiomyocyte transverse YM in healthy and pathological states with different mechanical loading. Specifically, we show that posttranslational modifications of MTs have differing effects on cardiomyocyte YM: Acetylation provides flexibility, whereas detyrosination imparts rigidity. Further studies demonstrate that there is no correlation between the total protein amount of acetylated and detyrosinated MT. Yet, in the polymerized-only populations, an increased level of acetylation results in a decline of detyrosinated MTs in an MI model.

Abstract:

If a piece of homogeneous anisotropic elastic material is subject to simple tension along a direction n for which Young’s modulus E(n) is an extremum, then the corresponding strain field is coaxial with the simple tension stress field. An appropriate set of rectangular cartesian coordinate axes may be introduced such that three of the elastic compliances are zero. In this coordinate system the displacement field may be written explicitly and corresponds to a pure homogeneous deformation.

In this paper the vibration testing and Fast Fourier Transform(FFT) analysis detection on the basis of nondestructive testing method were analyzed. The dynamic Young’s modulus of the regeneration pre-sensitized offset plate were obtained by using the nondestructive testing methods, including the dynamic Young’s modulus by longitudinal vibration method, the dynamic Young’s modulus by out-plane flexural vibration method, and the dynamic Young’s modulus by in-plane flexural vibration method. The linear correlativity was investigated between the dynamic Young’s modulus and the modulus of elasticity(MOE) for the regeneration pre-sensitized offset plate.The linear correlations between the dynamic Young’s modulus and the MOE were good. So it is feasible to predict and analyze the plate mechanical properties put forward the nondestructive testing method of key mechanical performance parameters.

Abstract:

Based on the semi-continuum model, the effect of temperature on Young’s modulus in the presence of oxide layer in silicon nano-films was studied theoretically by using the anharmonic Keating deformation potential, and the effect of oxide layer on Young’s modulus was also studied. The results show that Young’s modulus of the nano-film is inversely proportional to its temperature, which decreases with the increase of temperature. And with the number of oxide layer increasing, Young’s modulus of silicon nano-film increases. At the same thickness and layer numbers, Young’s modulus of the films with oxide layer is larger than that of pure silicon nano-films. The existence of oxide layer leads to the increase of Young’s modulus of the silicon nano-film.

Full text

Abstract:

A nondestructive measurement method based on an Optical frequency domain reflectometry (OFDR) was demonstrated to achieve Young’s modulus of an optical fiber. Such a method can be used to measure, not only the averaged Young’s modulus within the measured fiber length, but also Young’s modulus distribution along the optical fiber axis. Moreover, the standard deviation of the measured Young’s modulus is calculated to analyze the measurement error. Young’s modulus distribution of the coated and uncoated single mode fiber (SMF) samples was successfully measured along the optical fiber axis. The average Young’s modulus of the coated and uncoated SMF samples was 13.75 ± 0.14, and 71.63 ± 0.43 Gpa, respectively, within the measured fiber length of 500 mm. The measured Young’s modulus distribution along the optical fiber axis could be used to analyze the damage degree of the fiber, which is very useful to nondestructively estimate the service life of optical fiber sensors immersed into smart engineer structures.

Full text

Abstract:

Dynamical thermomechanical analysis of 5 illite-based clays from deposits in Slovakia, Estonia, Latvia, and Hungary is presented. The clays consist of illite (37–80 mass%), quartz (12–48 mass%), K-feldspar (4–13 mass%), kaolinite (0–18 mass%), and calcite (0–3 mass%). Young’s modulus is measured during the heating and cooling stages of firing (25 °C → 1100 °C → 25 °C). The liberation of the physically bound water increases Young’s modulus by ∼70% for all studied clays. By increasing the temperature, dehydroxylation and the α → β transition of quartz take place without a significant effect on Young’s modulus. Sintering, which starts at 800 °C, leads to an intensive increase in Young’s modulus up to the highest temperature (1100 °C). The increase remains also in the early stage of cooling (1100 °C → 800 °C). This increase of Young’s modulus is also the result of solidification of the glassy phase, which is finished at ∼750 °C. A sharp minimum of Young’s modulus is observed at around the β → α transition of quartz. Then, Young’s modulus still decreases its value down to the room temperature. The physical processes observed during heating and cooling do not differ in nature for the studied clays. Values of Young’s modulus vary at around 8 GPa, up to 800 °C. During sintering, Young’s modulus reaches values from 30 GPa to 70 GPa for the studied clays. The microstructure and composition given by the origin of the clay play a cardinal role for the Young’s modulus of the final ceramic body.

Full text

Abstract:

This study focuses on developing a pragmatic and robust method in the estimation of fracture orientation assuming a single set of aligned fractures. The Young’s modulus in the direction of fracture orientation is larger than that in the perpendicular direction that helps to solve the problem of the ambiguity in fracture-orientation estimation existing in the method of using the variation of amplitude-variation-with-offset (AVO) gradients with azimuth. First, the relationship between the Young’s modulus and fracture density and orientation is analyzed. The Young’s modulus changes regularly with the variation of incident angles and azimuth, and the changing track is a cosine curve when the incident angle is fixed. The variation of the Young’s modulus increases with the increase of fracture density. Second, we use the Young’s modulus variation with azimuth to predict the fracture orientation. The Young’s modulus inversion algorithm for different azimuths of prestack seismic data and the ellipse fitting of the Young’s moduli in different azimuth with the least-squares algorithm are included in this proposed approach. Finally, we determine the advantage and robustness of our method in fracture-orientation estimation with synthetic and real-data examples. Compared with the conventional methods using AVO gradients, the direction of longer axis of the fitting ellipse of the Young’s modulus in different azimuth indicates the fracture orientation without ambiguity.

Abstract:

Understanding the time-dependent behavior of rocks is important for ensuring the long-term stability of underground structures. Aspects of such a time-dependent behavior include the loading-rate dependency of Young’s modulus, strength, creep, and relaxation. In particular, the loading-rate dependency of Young’s modulus of rocks has not been fully clarified. In this study, four different types of rocks were tested, and the results were used to analyze the loading-rate dependency of Young’s modulus and explain the underlying mechanism. For all four rocks, Young’s modulus increased linearly with a tenfold increase in the loading rate. The rocks showed the same loading-rate dependency of Young’s modulus. A variable-compliance constitutive equation was proposed for the loading-rate dependency of Young’s modulus, and the calculated results agreed well with measured values. Irrecoverable and recoverable strains were separated by loading-unloading-reloading tests at preset stress levels. The constitutive equations showed that the rate of increase in Young’s modulus increased with the irrecoverable strain and decreased with increasing stress. The increase in the irrecoverable strain was delayed at high loading rates, which was concluded to be the main reason for the increase in Young’s modulus with an increasing loading rate.

A method for determining the flexural Young’s modulus of polymeric materials from deformation diagrams of thin-walled circular cylindrical shells in compression in the region of geometrical nonlinearity has been elaborated. A numerical solution is found by the finite-element method (ANSYS.) The existence of a unified deformation diagram in generalized coordinates is established, from which the flexural Young’s modulus is determined. To validate the method, the Young’s modulus of specimens was found experimentally.

Abstract:

The relationship between textures and Young’s modulus in CVD diamond films was simulated based on the phenomenological theory, which indicates the textures induce the Young’s modulus anisotropy. The increase of methane concentration changes the density of different fiber textures in diamond films, which induces the increase of Young’s modulus in the directions that parallel to the film surface. Among the textures, {111} texture is of no influence whereas {011} texture has the maximum influence on the Young’s modulus anisotropy of diamond film.

Abstract:

A grain is surrounded by grains with different crystal orientations in polycrystalline plain low-carbon steel. The grain is constrained by its adjacent grains in the tension process. The interaction of the grain with the adjacent grains was investigated within the elastic deformation region. The following results have been obtained: (1) the Young’s modulus of a grain without consideration of grain-to-grain interaction is denoted as the inherent Young’s modulus; when the inherent Young’s modulus of a grain is equal to the Young’s modulus of the bulk material, there is almost no interaction between the grain and its adjacent grains; when a grain has a great difference between its inherent Young’s modulus and the Young’s modulus of the bulk material, its grain-to-grain interactions increase significantly; (2) the grain-to-grain interaction is mainly caused by the difference in the inherent Young’s modulus between the grain and its adjacent grains; the misorientation angle between the grain and its adjacent grains has almost no effect on the grain-to-grain interaction.

In order to study the thallus changes on microscopic morphology and mechanical properties ofCandida albicansantagonized byStreptococcus sanguinisbacteriocin, the adhesion ability and Young’s modulus of thalli and hypha ofCandida albicanswere measured by the relative measurement method using atomic force microscope’s (AFM) tapping model. The results showed that the average adhesion ability and Young’s modulus of thalli were7.35±0.77 nN and7.33±1.29 Mpa, respectively; the average adhesion ability and Young’s modulus of hypha were9.82±0.39 nN and4.04±0.76 Mpa, respectively. After being antagonized byStreptococcus sanguinisbacteriocin, the adhesion ability was decreased along with the increasing of deformation in reaction region and Young’s modulus followed the same changes. It could be concluded that the adhesion ability of hypha was greater than thalli, Young’s modulus of hypha was less than thalli, and adhesion ability and Young’s modulus ofCandida albicanswere decreased significantly after being antagonized byStreptococcus sanguinisbacteriocin.

Abstract:

Thermal barrier coatings(TBCs) has been extensively used on hot section components of gas turbine engine, especially turbine blades. Young’s modulus of TBCs is a significant mechanical parameter in life prediction research of turbine blades, but it is hard to measure the EB-PVD thermal barrier coatings by conventional tensile/compression method for its brittleness and porous microstructure. Therefore, Young’s modulus mathematical model of double-layer beam structure specimen was deduced on the basis of the first-order beam bending vibration equation and composite beam bending equation. An experimental platform with dynamic signal acquisition system was set up for measuring Young's modulus of thermal barrier coatings under high temperature. Young's modulus of ceramic coat was measured from ambient temperature to 1100°C to provide material data for subsequent research on life prediction of turbine blades with thermal barrier coatings.

Abstract:

In this paper, the influencing factors of the Young’s modulus of coals were investigated by measuring the stress-strain behaviors under different confining stress and water ratio conditions and constituents for 13 anthracite coal samples obtained from the southern Qinshui basin of China. The results show that: (1) For a coal, its Young’s modulus increases in the form of convex increasing parabolic curve with increasing confining stress acting on the coal but reduces with increasing water ratio in the form of convex decreasing parabola. (2) The Young’s modulus of coals is negatively proportional to fixed carbon and vitrite contents; while it positively related to inertite content. The Young’s modulus of coals becomes remarkable when ash yield is of larger than about 11%. The coals with 60% vitrinite and 40% inertinite contents have the maximum Young’s modulus.

Abstract:

Purpose. Experimental finding of Young’s modulus values of the specimen of steel 09Г2С with weld longitudinal arrangement and of the basic metal, which is used for box girder manufacturing, by means of non-electrical strain measurement under various loads. Comparison of the received results among themselves and with data of references. Methods of research. Experiment, strain measurement, least-squares technique. Results. Several metal strips of steel 09Г2С arranged crosswisely have been welded for making of a specimen. The specimen of steel 09Г2С with weld longitudinal arrangement and rectangular cross-section has been produced of the received detail by milling with cooling. Tests have been executed on calibrated equipment for finding of Young’s modulus values of the weld and of the basic metal. Strains have been measured by Huggenberger tensometer during experiment. Experimental results have been processed by least-squares technique. The received results have been compared among themselves and with data of references. It has been found out, that Young’s modulus values of the basic metal on all references are comparable, but differ one from another. Young’s modulus values of the weld differ essentially. Weld Young’s modulus is a little bigger than basic metal Young’s modulus according to experimental data of other author. Weld Young’s modulus is a little smaller than basic metal Young’s modulus according to the received experimental data. This difference can be explained, in particular, by different ways of production of specimens for finding of weld Young’s modulus. Scientific novelty. Young’s modulus values of the specimen of steel 09Г2С with weld longitudinal arrangement has been experimentally found by means of mechanical strain measurement under various loads and with result processing by least-squares technique. Practical value. Experimentally found Young’s modulus values of the weld of the basic metal are necessary at physical and mathematical modelling of a stress state of a box girders of steel 09Г2С.

Abstract:

Mice harboring the Col1a2 oim mutation ( oim) express dentinogenesis imperfecta. To determine the effect of Col1a2 genotype on tissue mechanical properties, we compared Young’s modulus and hardness of dentin in the 3 Col1a2 genotypes. Upper incisors were tested by nanoindentation. Genotype had a significant effect on Young’s modulus, but there was not a simple mutant allele dosage relationship. The effect of genotype on hardness did not reach significance. Hardness and Young’s modulus were greater near the dento-enamel junction than near the pulp chamber. Greater hardness and Young’s modulus values near the dento-enamel junction reflected continued mineralization of the dentin following its initial synthesis. Analysis showed the mechanical data to be consistent with Fourier transform infrared and backscattered electron microscopy studies that revealed increased mineralization in oim bone. Analysis of the data suggests that clinical fragility of teeth in oim mice is not due to deficiencies of hardness or Young’s modulus, but may be due to defects in post-yield behavior or resistance to fatigue damage.

Abstract:

Young’s modulus (E) is one of the most important parameters in the mechanical properties of solid materials. Young’s modulus is proportional to the stress and strain values. There are several experimental and theoretical methods for gaining Young’s modulus values, such as stress–strain curves in compression and tensile tests, electromagnetic-acoustic resonance, ultrasonic pulse echo and density functional theory (DFT) in different basis sets. Apparently, preparing specimens for measuring Young’s modulus through the experimental methods is not convenient and it is time-consuming. In addition, for calculating Young’s modulus values by software, presumptions of data and structures are needed. Therefore, this new method for gaining the Young’s modulus values of crystalline materials is presented. Herein, the new method for calculating Young’s modulus of crystalline materials is extracted by X-ray diffraction. In this study, Young’s modulus values were gained through the arbitrary planes such as random (hkl) in the research. In this study, calculation of Young’s modulus through the relationship between elastic compliances, geometry of the crystal lattice and the planar density of each plane is obtained by X-ray diffraction. Sodium chloride (NaCl) with crystal lattices of FCC was selected as the example. The X-ray diffraction, elastic stiffness constant and elastic compliances values have been chosen by the X’Pert software, literature and experimental measurements, respectively. The elastic stiffness constant and Young’s modulus of NaCl were measured by the ultrasonic technique and, finally, the results were in good agreement with the new method of this study. The aim of the modified Williamson–Hall (W–H) method in the uniform stress deformation model (USDM) utilized in this paper is to provide a new approach of using the W–H equation, so that a least squares technique can be applied to minimize the sources of errors.

Abstract:

The force-displacement curves of rat’s red blood cells (RBC) were measured by atomic force microscope (AFM) in this study, and the young’s modulus of RBC were calculated. The different speed and loads of probe on AFM was conducted to exam the effect of young’s modulus in RBC. Furthermore, the relationship between young’s modulus of RBC and different depth of indentation from force-displacement curves were investigated. The experimental results and analysis showed that when probe’s maximum load was 5 nN and the velocity was set for 1, 5, 10 and 20 μm/s, the young’s modulus of normal red blood cells for probe down measurements to AFM were 129.56 ± 42.80, 141.56 ± 31.15, 147.90 ± 24.35 and 149.69 ± 29.27 kPa, respectively. It represented that the young’s modulus of normal red blood cells depended on probe’s velocity. Then when probe’s velocity was 1 μm/s and the load was changed to 1, 5 and 10 nN, the young’s modulus of normal red blood cells were measured for 41.45 ± 22.64, 82.72 ± 53.99 and 202.40 ± 16.01 kPa, respectively. It represented that the young’s modulus of normal red blood cells depended on the probe’s load. On the other side, the results of force-displacement curves exam demonstrated that the deeper of probe indented in cells, the measured young’s modulus of normal red blood cells would be increased more.

Abstract:

Contact curvature plays a pivotal role in the Young’s modulus determination and mechanical response of a particle. This paper presents the sensitivity analysis of a particle morphology to contact curvature and its influence on the Young’s modulus determination during the elastic deformation of a particle. X-ray computed micro-tomography (μCT) was conducted to obtain the prototype of a single particle. The digital information of the scanned particle, including 2D slices and 3D rendering was processed and the variation of contact curvature of the particle was examined using the circular (spherical at 3D) and polynomial fitting methods. The fitting sections of the particle are taken into account. The effect of contact curvature on Young’s modulus determination was investigated and it was found that Young’s modulus changed substantially from global fitting to local fitting. Young’s modulus is highly related to the surface roundness, which exerts a significant influence on the determination of Young’s modulus.

Abstract:

Abstract The tensile stress and strain under small deformation for plastics/elastomer blends were analyzed, based on a geometric model and mechanical element model, and a Young’s modulus equation was derived based on the hypothesis with equal strain and Hooke’s law. The polypropylene (PP)/polyolefin elastomer (POE) blends were prepared by means of a twin screw extruder, and the Young’s modulus was measured at room temperature. It was found that the Young’s modulus decreased nonlinearly with increase in the POE volume fraction. The Young’s modulus of the PP/POE blends was estimated using the equation and was compared with the measured data. There was good agreement between them. Moreover, the Young’s modulus of PP/ethylene propylene diene monomer (EPDM) rubber EPDM blends at room temperature was estimated respectively using this equation and the mingling rule equation, as well as Liang’s equation published in the literature. The results showed that the calculations with this equation were closer to the experimental data reported in reference than those with the other two equations.

Abstract:

Few studies have focused on determining the Young’s modulus of 3D printed structures. This study presents the results of experimental investigations of Young’s modulus of a 3D printed mortar. Specimens were prepared in four different ways to investigate possible application of different methods for 3D printed structures. Study determines the influence of the number of layers on mechanical properties of printed samples. Results have shown a strong statistical correlation between the number of layers and value of Young’s modulus. The compressive strength and Young’s modulus reduction compared to standard cylindrical sample were up to 43.1% and 19.8%, respectively. Results of the study shed light on the differences between the current standard specimen used for determination of Young’s modulus and the specimen prepared by 3D printing. The community should discuss the problem of standardization of test methods in view of visible differences between different types of specimens.

Abstract:

Young’s modulus of a silicon nanobeam with a rectangular cross-section is studied by molecular dynamics method. Dynamic simulations are performed for doubly clamped silicon nanobeams with lengths ranging from 4.888 to 12.491 nm and cros-sections ranging from 1.22 nm × 1.22 nm to 3.39 nm × 3.39 nm. The results show that Young’s moduli of such small silicon nanobeams are much higher than the value of Young’s modulus for bulk silicon. Moreover, the resonant frequency and Young’s modulus of the Si nanobeam are strongly dependent not only on the size of the nanobeam but also on surface effects. Young’s modulus increases significantly with the decreasing of the thickness of the silicon nanobeam. This result qualitatively agrees with one of the conclusions based on a semicontinuum model, in which the surface relaxation and the surface tension were taken into consideration. The impacts of the surface reconstruction with (2 × 1) dimmers on the resonant frequency and Young’s modulus are studied in this paper too. It is shown that the surface reconstruction makes the silicon nanobeam stiffer than the one without the surface reconstruction, resulting in a higher resonant frequency and a larger Young’s modulus.

Abstract:

This work reports the results of Young’s modulus of elasticity obtained for 3 types of engineered stones. Using parallelepiped specimens with dimensions 150  30  20 mm3, Young’s modulus is determined by different methods: static and dynamic. Via quasi-static deformation tests: - uniaxial tension, - uniaxial compression, and, - pure bending (i.e. symmetrical four-point bending), determination of Young’s modulus was carried out by means of the conventional electric-resistance extensometry with strain-gauge strips glued to the specimens. The results obtained from these quasi-static deformation tests are compared with the results of dynamic Young’s modulus obtained with RFDA equipment (Resonant Frequency & Damping Analyser) using the parallelepiped specimens in a flexural vibration mode. Dynamic Young’s modulus was also evaluated through measurements of ultrasonic pulses velocity. Composition and microstructures of the materials under investigation are also presented and discussed.

Abstract:

In order to reveal variation of mechanical properties of hepatoma cells with nanometer resolution, atomic force microscopy (AFM)-based nanoindentation experiments are performed on hepatoma cell to derive Young’s modulus employing a corrected Hertz model. Under load conditions of nanoindentation force as 0.43809-0.73015nN and penetration rate as 0.4 Hz, the calculated value of Young’s modulus of hepatoma cells is 34.137±0.67kPa with a 95% confidence interval. The results demonstrate the Young’s modulus varies with the measurement position, and the center of cell possesses lower value than peripheral region. Variation of Young’s modulus is resulted from external reaction, which supports well the theory of cytoskeleton structure. Furthermore, the difference of Young’s modulus between normal cells and cancerous ones are also discussed, and it will provide possibility of a new route for early diagnosis of hepatoma.

Abstract:

Young’s Modulus of glass fiber reinforced composites for wind energy applications are studied using numerical method. The effect of volume content of glass fiber on the Young’s modulus of composites is investigated. Results indicate the relation between them is nearly linear. In order to explore the effect of inclined angle of fiber on the Young’s modulus of composites, different finite element models with inclined glass fiber are developed via the ABAQUS Scripting Interface. Results indicate that Young’s modulus of the composites strongly depends on the inclined angle of fiber. A U-shaped dependency of the Young’s modulus of composites on the inclined angle of fiber is found, which agree with the experimental results. The results of the investigation are expected to provide some design guideline for the microstructural optimization of the glass fiber reinforced composites.

Abstract:

Young’s modulus and Poisson’s ratio are related to quantitative reservoir properties such as porosity, rock strength, mineral and total organic carbon content, and they can be used to infer preferential drilling locations or sweet spots. Conventionally, they are computed and estimated with a rock physics law in terms of P-wave, S-wave impedances/velocities, and density which may be directly inverted with prestack seismic data. However, the density term imbedded in Young’s modulus is difficult to estimate because it is less sensitive to seismic-amplitude variations, and the indirect way can create more uncertainty for the estimation of Young’s modulus and Poisson’s ratio. This study combines the elastic impedance equation in terms of Young’s modulus and Poisson’s ratio and elastic impedance variation with incident angle inversion to produce a stable and direct way to estimate the Young’s modulus and Poisson’s ratio, with no need for density information from prestack seismic data. We initially derive a novel elastic impedance equation in terms of Young’s modulus and Poisson’s ratio. And then, to enhance the estimation stability, we develop the elastic impedance varying with incident angle inversion with damping singular value decomposition (EVA-DSVD) method to estimate the Young’s modulus and Poisson’s ratio. This method is implemented in a two-step inversion: Elastic impedance inversion and parameter estimation. The introduction of a model constraint and DSVD algorithm in parameter estimation renders the EVA-DSVD inversion more stable. Tests on synthetic data show that the Young’s modulus and Poisson’s ratio are still estimated reasonable with moderate noise. A test on a real data set shows that the estimated results are in good agreement with the results of well interpretation.
