Abstract:
An experimental investigation was conducted to evaluate the compressive, tensile strength and modulus of elasticity of two-stage concrete (TSC) at different water-to-cement ratios. The primary objectives were to measure the elastic modulus, compressive strength and splitting tensile strength of TSC and to determine if there is a quantifiable relationship between compressive and tensile strength. Behavior of TSC in compression has been well documented, but there are little published data on its behavior in tension and modulus of elasticity. This paper presents the experimental results of preplaced, crushed granite aggregate concreted with five different mortar mixture proportions. A total of 48 concrete cylinders were tested in unconfined compression modulus of elasticity and splitting tension at 28 and 90 days. It was found that the modulus of elasticity and splitting tensile strength of two-stage concrete is equivalent or higher than that of conventional concrete at the same compressive strength. Splitting tensile strength can be conservatively estimated using the ACI equation for conventional concrete.

Abstract:
The testing experiments to healthy poplar and larch logs samplings were conducted by using hydraulic machine. The relationships among compression and bending strength, modulus of elasticity in compression and bending were studied in the two logs samplings. The results indicated that, in the both species, the compression strength had certain linear correlation with bending strength, and so did the modulus of elasticity in compression and bending. Meanwhile there were remarkable linear correlations with the compression strength and the modulus of elasticity in compression as well as the bending strength and the modulus of elasticity in bending.

Abstract:
The objective of this study is to evaluate experimentally the mechanical compressive strength and static modulus of elasticity of concrete pavers for floors made with iron ore tailings as aggregate concrete. Pavers were manufactured with four different concrete mixtures (cement, natural sand, industrial sand, iron ore tailings, crushed stone), and performed simple compression tests to determine the compressive strength and modulus of elasticity. The pavers manufactured with those concrete mixtures showed greater strength specified by the Brazilian standard. It was possible to find a correlation between modulus of elasticity and compressive strength.

Abstract:
Uniaxial compression test of cement asphalt (CA) mortar specimens, due to drying and wetting cycle of 0, 2, 4 and 8 times, is carried out by using the electronic universal test machine, with the strain rate ranging from 1 × 10−5 s−1to 1 × 10−2 s−1. The effects of strain rate and drying and wetting cycle time on the compressive strength, elasticity modulus, and stress-strain full curve are investigated. Experimental results show that the strain-stress full curve of CA mortar is affected obviously by strain rate and drying and wetting cycle time. The compressive strength and elasticity modulus increase with the strain rate under the same drying and wetting cycle time. The compressive strength and elasticity modulus decrease with the increase of drying and wetting cycle time in the same strain rate. The lower the strain rate is, the greater the compressive strength and elasticity modulus of CA mortar decrease. When the strain rate is 1 × 10−5 s−1and drying and wetting cycle time is 8, the largest reduction of average compressive strength of CA mortar is 40.48%, and the largest reduction of elasticity modulus of CA mortar is 35.51%, and the influence of drying and wetting cycle on the compressive strength of CA mortar is greater than its influence on the elasticity modulus.

The paper deals with the determination of the modulus of elasticity in tension for cementitious composites and comparing these values with the values of modulus in compression. It describes several methods, which are usually used for determination of modulus of elasticity of concrete and fibre reinforced concrete. In the experimental program modulus of elasticity in compression and tension of various types of concrete and fibre reinforced concrete were compared. The classic test with prismatic specimens was used for determination of the modulus in compression; a new arrangement of uniaxial tension test of cementitious composites was used for determination of the modulus of elasticity in tension.

The modulus of elasticity is an important property for the behavior analysis of concrete structures. This research evaluated the strain difference between concrete specimens with and without the application of laminate carbon fiber composites as well as the variation time, in months, of the axial strength compression and modulus of elasticity. Through the experimental results, it is concluded that increases in compressive strength and modulus of elasticity are more significant in the specimens without reinforcement.

Compression strength and other mechanical properties of particleboards induced by density. The aim of the paper was to investigate the contractual compression strength and modulus of elasticity under compression of six types of commercially available particleboards of various thickness, density and surface finish. The basic mechanical and physical characteristics of the tested panels (modulus of elasticity and modulus of rupture during bending, density and density profile) were also performed. The studies showed that the compression strength raises linearly with panels’ density raise, and the modulus of elasticity under compression is linearly opposite, depending on the panels’ density.

Abstract:
A nonlinear three-dimensional finite element model was developed to study the complex behavior of ungrouted and grouted concrete block masonry prisms under axial compression. The model detects crack initiation and traces crack propagation in the masonry assemblage. Variable strengths for blocks, mortar, and grout were used to study the effect of the mechanical properties of prism constituents, and their combinations, on the prism strength and modulus of elasticity. The effect of the number of courses was also investigated. The results of the finite element analysis were used to develop simplified relationships to predict prism strength and modulus of elasticity. Good agreement was observed between the available experimental data and the predicted prism strengths. Key words: compressive strength, concrete blocks, failure modes, finite element, masonry, modulus of elasticity, prisms.

Abstract:
Experimental study on the development of strength and modulus of elasticity of cement-treated aggregate base (CTAB) materials was undertaken. Unconfined uniaxial compression tests were conducted with 189 samples for 16 CTAB mixtures at different ages. Two different aggregates, conventional crushed limestone base and recycled concrete materials, were used in the test program. Using the test results, equations were proposed to estimate the development of compressive strength and modulus of elasticity of CTAB materials with time. Test results indicated that the relationship between the compressive strength and elastic modulus of CTAB materials could be expressed in a single equation regardless of aggregate type and mixture proportions.

Abstract:
The paper focuses on the influence of the standard test method applied to determine the concrete stabilized secant modulus on a specified value. The new European Standard EN 12390-13 for testing hardened concrete accepts two methods (A and B) for the determination of the secant modulus of elasticity in compression. The aim of the research was to establish how different testing procedures affect a measured value of modulus of elasticity. Four structural concrete series: two lightweight aggregate concretes and two normal-weight ones were subject to tests of moduli of elasticity determined by both standard methods, as well as compressive strength and density. The carried out tests revealed that the procedure of testing modulus of elasticity influenced a measured value. Method A led to higher values of modulus in relation to Method B, irrespective of concrete density and strength. Nevertheless, a certain relationship between the concrete structure homogeneity and the difference in results of moduli determined by both methods may be observed.

Abstract:
La determinazione del modulo di Young è fondamentale nello studio della propagazione di fratture prima del rilascio di una valanga e per lo sviluppo di affidabili modelli di stabilità della neve. Il confronto tra simulazioni numeriche del modulo di Young e i valori sperimentali mostra che questi ultimi sono tre ordini di grandezza inferiori a quelli simulati (Reuter et al. 2013)⁠. Lo scopo di questo lavoro è stimare il modulo di elasticità studiando la dipendenza dalla frequenza della risposta di diversi tipi di neve a bassa densità, 140-280 kg m-3. Ciò è stato fatto applicando una compressione dinamica uniassiale a -15°C nel range 1-250 Hz utilizzando il Young's modulus device (YMD), prototipo di cycling loading device progettato all'Istituto per lo studio della neve e delle valanghe (SLF). Una risposta viscoelastica della neve è stata identificata a tutte le frequenze considerate, la teoria della viscoelasticità è stata applicata assumendo valida l'ipotesi di risposta lineare della neve. Il valore dello storage modulus, E', a 100 Hz è stato identificato come ragionevolmente rappresentativo del modulo di Young di ciascun campione neve. Il comportamento viscoso è stato valutato considerando la loss tangent e la viscosità ricavata dai modelli di Voigt e Maxwell. Il passaggio da un comportamento più viscoso ad uno più elastico è stato trovato a 40 Hz (~1.1•10-2 s-1). Il maggior contributo alla dissipazione è nel range 1-10 Hz. Infine, le simulazioni numeriche del modulo di Young sono state ottenute nello stesso modo di Reuter et al.. La differenza tra le simulazioni ed i valori sperimentali di E' sono, al massimo, di un fattore 5; invece, in Reuter et al.⁠, era di 3 ordini di grandezza. Pertanto, i nostri valori sperimentali e numerici corrispondono meglio, indicando che il metodo qui utilizzato ha portato ad un miglioramento significativo.

Abstract:
This paper presents results on experimental research for concrete produced using recycled coarse aggregates (RCA). Five types of coarse aggregates were used in this study, four of which were RCA. The main purpose of this research was to examine how different types and properties of coarse aggregate affected compressive strength, modulus of elasticity, and shrinkage in concrete when natural coarse aggregates were replaced with RCA. Concrete batches were made with water-cement (w/c) ratios of 0.30, 0.45, and 0.60, and substitution percentages ranged from 0% to 100% of natural aggregate with RCA. Test results clearly show that compressive strength, modulus of elasticity, and shrinkage greatly depend on the quality and type of coarse aggregate used. In addition to testing of hardened concrete, predictive models for elasticity and ultimate shrinkage were developed to formulate and reinforce proposed conclusions about the properties and performance for the different RCA.

Abstract:
Detta examensarbete presenterar resultat från en laboratoriestudie på en lera från Enköping stabiliserad med kalk och cement. I laboratoriet har isotropiskt konsoliderade odränerade aktiva triaxialförsök utförts på provkroppar och jämförts med enaxliga tryckförsök som utförts på provkroppar från samma inblandningstillfälle. De två metoderna har visat sig ge likvärdiga värden på utvärderad odränerad skjuvhållfasthet. Elasticitetsmodulen har däremot visat sig vara mycket högre för triaxialförsöken än enaxliga tryckförsök. För triaxialförsöken har förhållandet mellan sekantmodulen och den odränerade skjuvhållfastheten legat mellan 112-333. För de enaxliga tryckförsöken ligger förhållandet mellan sekantmodulen och den odränerade skjuvhållfastheten inom intervallet 44-146. Inget mönster har dock kunnat urskiljas då förhållandet mellan de två olika försöken har varierat mellan 1,0-3,5. Ett lägre och högre back pressure användes under triaxialförsöken. Till skillnad från tidigare studier har dock båda dessa back pressures vattenmättat provkroppen. Resultaten visar på att back pressure inte påverkar testresultaten, förutsatt att provet blivit fullt vattenmättat. Utöver denna jämförelse har ytterligare passiva triaxialförsök utförts. De passiva triaxialförsöken har utförts som isotropiskt konsoliderade odränerade försök.. Däremot har två olika metoder använts under skjuvningsfasen. I första typen av försök har den axiella spänningen minskats medan den radiella spänningen har hållits konstant. I den andra typen av försök har i stället den radiella spänningen ökats samtidigt som den axiella spänningen har hållits konstant. Skjuvhållfastheter har jämförts med resultat från kalkpelarsondering i fält och visar på att skjuvhållfastheten genomgående varit högre i fält än i laboratoriet. Dessutom har skjuvhållfastheter och elasticitetsmoduler testats efter olika lagringstider genom enaxliga tryckförsök.
This master thesis presents results from a laboratory study on a clay from Enköping which was stabilized with lime and clay. Isotropic consolidated undrained compressive tests were performed on samples and compared to unconfined compressive testing. The two methods have shown no difference in the evaluation of undrained shear strength. However the modulus of elasticity was shown to be much higher for the triaxial tests. For the unconfined compressive tests the relation between the undrained shear strength and secant modulus was within the range of 44-146. The equivalent for the triaxial tests was in the interval of 112-333. However no pattern was extinguishable between the two tests as this relation has varied between 1,0 to 3,5. A lower and higher back pressure was used during the triaxial testing. However, both back pressures have succeeded in saturating the sample. Results show that the back pressure has little effect on the results, as long as the sample has been fully saturated. In addition to this extension tests were performed on samples as well. The tests performed were isotropic consolidated undrained. However two different shearing methods were used. The first test was strain rate dependant while the second test was stress rate dependant. In the first test the vertical stress decreased while the radial stresses were kept constant, while in the other test the radial stresses increased while the vertical stress were kept constant. The undrained shear strength was compared to lime/cement column penetration tests in field. Results showed that tests in field show a much higher undrained shear strength than laboratory testing.

The thesis deals with the measurement of the elastic modulus of concrete in existing structures and possibilities of applicability of equations for the calculation of characteristic values of concrete compressive strength on the modulus of elasticity. The modulus of elasticity is determined by dynamic and static methods on specimens taken from the concrete blocks, whose composition varies by a water cement ratio and varying amounts of admixtures. In conclusion, the results of the measurements are compared and the characteristic values of the modulus of elasticity is determined.

Abstract:
In recent times, light gauge cold-formed steel sections have been used extensively in residential, industrial and commercial buildings as primary load bearing structural components. This is because cold-formed steel sections have a very high strength to weight ratio compared with thicker hot-rolled steel sections, and their manufacturing process is simple and cost-effective. However, these members are susceptible to various buckling modes including local and distortional buckling and their ultimate strength behaviour is governed by these buckling modes. Fire safety design of building structures has received greater attention in recent times due to continuing loss of properties and lives during fires. Hence, there is a need to fully evaluate the performance of light gauge cold-formed steel structures under fire conditions. Past fire research has focused heavily on heavier, hot-rolled steel members. The buckling behaviour of light gauge cold-formed steel members under fire conditions is not well understood. The buckling effects associated with thin steels are significant and have to be taken into account in fire safety design. Therefore, a research project based on extensive experimental and numerical studies was undertaken at the Queensland University of Technology to investigate the distortional buckling behaviour of light gauge cold-formed steel compression members under simulated fire conditions. As the first phase of this research program more than 115 tensile coupon tests of light gauge cold-formed steels including two steel grades and five thicknesses were conducted at elevated temperatures. Accurate mechanical properties including the yield strength, elasticity modulus and stress-strain curves were all determined at elevated temperatures since the deterioration of the mechanical properties is one of the major parameters in the structural design under fire conditions. An appropriate stress-strain model was also developed by considering the inelastic characteristics. The results obtained from the tensile coupon tests were then used to predict the ultimate strength of cold-formed steel compression members. In the second phase of this research more than 170 laboratory experiments were undertaken to investigate the distortional buckling behaviour of light gauge coldformed steel compression members at ambient and elevated temperatures. Two types of cross sections were selected with various thicknesses (nominal thicknesses are 0.6, 0.8, and 0.95 mm) and both low and high strength steels (G250 and G550 steels with minimum yield strengths of 250 and 550 MPa). The experiments were conducted at six different temperatures in the range of 20 to 800°C. A finite element model of the tested compression members was then developed and validated with the help of experimental results. The degradation of mechanical properties with increasing temperatures was included in finite element analyses. An extensive series of parametric analyses was undertaken using the validated finite element model to investigate the effect of all the influential parameters such as section geometry, steel thickness and grade, mechanical properties and temperature. The resulting large data base of ultimate loads of compression members subject to distortional buckling was then used to review the adequacy of the current design rules at ambient temperature. The current design rules were reasonably accurate in general, but in order to improve the accuracy further, this research has developed new design equations to determine the ultimate loads of compression members at ambient temperature. The developed equation was then simply modified by including the relevant mechanical properties at elevated temperatures. It was found that this simple modification based on reduced mechanical properties gave reasonable results, but not at higher temperatures. Therefore, they were further modified to obtain a more accurate design equation at elevated temperatures. The accuracy of new design rules was then verified by comparing their predictions with the results obtained from the parametric study. This thesis presents a description of the experimental and numerical studies undertaken in this research and the results including comparison with simply modified current design rules. It describes the laboratory experiments at ambient and elevated temperatures. It also describes the finite element models of cold-formed steel compression members developed in this research that included the appropriate mechanical properties, initial geometric imperfections and residual stresses. Finally, it presents the details of the new design equations proposed for the light gauge coldformed steel compression members subjected to distortional buckling effects at elevated temperatures.

Abstract:
Sweetgum, Liquidambar styraciflua, is a diffuse-porous hardwood occurring in the southeastern United States. In this observational study, trees from two plantations of sweetgum were evaluated for mechanical properties. The two plantations were similar in age, soil type, competition control, and water availability, but differed in nutrient availability, growing season, and growth rate. Three trees representing different crown classes were removed from both plantations. Each tree was sampled for compression strength parallel to grain along the height of the merchantable stem. Oven-dry specific gravity was then calculated for each sample. The results indicate that young sweetgum trees grow weaker wood than mature trees. It was observed that dominant trees were stronger and denser than other trees. Denser wood was formed in the plantation with the shortest growing season and smallest growth rate. Three of six trees showed significant correlations of strength and stiffness with height in the tree.

Abstract:
Abstract Present design of large laminated magnets are based on effective modulus of elasticity for the plate stack that is invariant with interplate compression. Experimental results indicates this is not a valid assumption. This analysis considers the specific design used for compact electron storage ring dipole magnet at the Center for Advanced Micro Devices (CAMD) at Louisiana State University. An iterative technique, using FEM is developed to approximate the effective modulus throughout the magnet structure. This particular magnet is constructed from 1424 steel plates (1.5mm × 610mm × 780mm) by first compressing a 45° 2.93m raduis curvilinear stack to a specified preload and then welding straight and curved straps to the exterior of the stack. Release of the preload allowsexpansion of the stack and forces stretch of the straps, the resultant interplate compression is considerably different from the initial preload and varies throughout the magnet. The analysis technique introduced in this paper is a simplified approach to the interplate compression modeling and consists of the supeposition of two simple analysis; one with straps attached, one without straps attached. An iterative approach is used to incorporate the dependence of effective compressive modulus on the interplate compression. An estimate of the average modulus is assumed for the entire stack and residual compression is calculated. From this residual compression and from experimental data, a distribution of compressive modulus throughout the magnet is computed. From this computed distribution, a new estimate for the compressive modulus is made for each element of the model and the analysis iterated. The net results are the compressive modulus distribution throughout the magnet ia a form suitable in subsequent dynamic analysis.

Abstract:
Mechanical loading has been implicated in regulating cellular behavior which in turn affect tissue development, growth, maintenance and regeneration. The structural components of the cell (cell membrane, transmembrane proteins such as integrins and at least three cytoskeletal networks of actin, microtubules and intermediate filaments) are involved in converting the mechanical loading into biochemical signals which then affect cellular behavior (1). Further, cells are known to alter their cytoskeletal structure during cell division (2), differentiation (3), pathology (4) and in response to mechanical loading (5). These changes will probably be reflected in gross material properties of the cell, such as modulus of elasticity. In this work, we describe a system to determine the modulus of elasticity of cells when they are embedded in agarose gel and subjected to compressive loading.

Abstract:
This experimental work evaluates the relationship between compressive strength and modulus of Elasticity of self-consolidating High performance concrete (SCHPC) containing high volume of Groundnut Shell Ash (GSA) up to 40% substitution as SCM. A total of 210 specimens of the GSA blended SCHPCs comprising 105 cubes (100 x100 mm) and 105 cylinders (150x300 mm) were cured in water for 7,14,28 ,56, 92,120 and 180 days hydration periods and the compressive strength and Modulus of elasticity determined. The linear relationships were studied with regression analysis. The findings revealed that all the mixes met the Modulus of Elasticity values requirement of 18,000N/mm2 to 42,000N/mm2 and the compressive results show that three substitution levels of 0%, 10% and 20% attained the proposed design strength (40-130 Mpa) and also satisfied the requirement for self-consolidating and high strength concretes. In conclusion, 0%-20% GSA substitutions (SCHPCA0-SCHPCA20) indicated a strong linear relationship with regressions values obtained varies between 0.842 and 0.954 for the two variables. Addition of GSA as SCM has improved the mechanical properties of SCHPC and creates a strong relationship between the compressive strength and Modulus of Elasticity.

Abstract:
Hydrogels have been used as substrates by many researchers in the study of cellular processes. The mechanical properties of these gels play a significant role in the growth of the cells. Significant research using several methods like compression, indentation, atomic force microscopy and manipulation of beads has been performed in the past to characterize the stiffness of these substrates. However, most of the methods employed assume the gel to be incompressible, with a Poisson’s ratio of 0.5. However, Poisson’s ratio can differ from 0.5. Hence, a more complete characterization of the elastic properties of hydrogels requires that one experimentally obtain the value of at least two of the three quantities: Poisson’s ratio, shear modulus, and elastic modulus.

Abstract:
The aim of this study is to quantitatively discern the compressive stiffness along the thickness of bovine cortical bone from the inner surface toward the bone’s periosteum (outer) surface. Ring-shaped bone slices from randomly selected 3 cow bovine bones were cut from mid diaphysis femur. Micro hardness measurements (ASTM E384-11e1 Standard- test method for Vickers hardness of materials with load of 500gf and dwelling time of 10s) were conducted along radial lines emanating from the geometric center of the bone transverse cross section. Values of compressive stiffness (longitudinal young’s modulus, E11) using the slope of the unloading curve of micro hardness tests at maximum load were extracted per the method advanced by Oliver and Pharr. Fitting these data points in a linear fit resulted in statistically significant and simple linear equations for compressive modulus as function of radial distance. For the anatomical anterior and posterior regions, compressive modulus values were found to range from 18 to 23.4 GPa (average of 21.2 GPa) and 23 to 26.0 GPa (average of 23.8 GPa), respectively. This is about 12% increase in average stiffness values of outer lamella near the periosteum as compared with inner regions.

Abstract:
The fuel injection and peak fuel injection pressures of a liquid fuel compression-ignition engine, such as a diesel engine or a diesel engine burning an alternative liquid fuel, are affected by fuel physical properties, and various engine design and operation input parameters. The fuel physical properties under this investigation include fuel density, fuel bulk modulus of elasticity, and fuel viscosity. The design and operation input parameters studied include the engine speed and the injector nozzle configuration parameters, such as the number of holes per injector nozzle, the dimensions of the hole, and the nozzle fuel flow discharge coefficient. The work of this paper analytically investigates the effects of those input parameters on pump-to-injector line fuel pressure and peak pressure. An understanding and simplified modeling of the fuel peak pressure affected by those property and input parameters are developed. The variations of the fuel pressure parameters over varying the fuel properties and the input parameters are analyzed and predicted. Results from this study indicate that, as the fuel bulk modulus of elasticity varies, the initial fuel pressure build-up period would be affected more significantly, with a less-significant variation in the fuel-line peak pressure. Among those fuel physical properties, the fuel density has a relatively significant effect on the fuel peak pressure. The effects of the various design and operation input parameters on the fuel peak pressure and related injection parameters are also studied and presented.

Abstract:
Abstract. Replacing cement with fly ash has recently created huge popularity among the construction field because of its huge production, efficient resources and sustainability aspect. This study is made to determine the High-Volume fly-ash concrete (HVFC) performance by adding additives. The general used concrete mixture is prepared by proportioning fly ash (40-50%) as a replacement. The concrete specimen was found to have better compressive strengths and hence, passed the strength tests. By incorporating additive Nano-SiO2 and superplasticizer the following compression, flexural rigidity, splitting tensile strength and elasticity modulus were observed in the specimen to establish the cement and fly ash bond. The concrete performance mix with replacement fly ash at different percent was found to have good compressive strength during test and stayed undamaged during the entire period of exposure.
