Abstract:
Measures taken against preventing damages in structures against explosive load are a popular matter of investigation among researchers. Generally, numerous studies were conducted on reinforcement materials for outer surfaces, reinforcement design, and utilizing fibers produced from various materials. In this study, a hollow-core slab was manufactured with concrete, which had a regular strength, and a design that discharged the explosive energy upon contact explosion via the hollow cores of the slabs and prevented the redirection of the explosive energy to the area below the slabs was investigated. Because the hollow-core slab in the study did not have any lateral reinforcement, the utilization of the tensile strength of the concrete proved advantageous. For this purpose, in the experimental tests of the study, contact explosions were conducted on hollow-core slabs with hollow diameters of 14 cm for each core. Before the explosion tests, the TNT equivalent of 910gr explosive was determined by performing the TNT equivalent tests. In the explosion tests of prepared hollow core concrete slabs, 125 gr, 250 gr, 375 gr, and 500 gr dynamites were used as the explosive materials. In conclusion, the explosive loads that the slabs could withstand were calculated and various slabs with distinctive hollow-core diameters were determined depending on the amount of the explosives.

Abstract Explosive welding is an effective method of joining of various metals and alloys. However, when the materials with very different strength and thermo-physical properties are welded or thin-layer cladding is performed, the difficulties occur which call for extra investigations. In the present paper, with the couples of steel / carbide composite and copper / hardened steel used as examples, under study were the peculiarities of bonding formation by the explosive welding of metals with highly differing properties. The experiments were carried out with emulsion explosive containing hollow micro-spheres and detonating in thin layers with the low (2 - 3 km/s) detonation velocity. Obtained results show that the emulsion explosives enable to extend the explosion welding potentiality.

Abstract:
A cylinder expansion test for high explosives was carried out to determine JWL parameters. Using the JWL parameters, we carried out numerical simulations of the underwater shock waves generated by the underwater explosion of the high explosives. Our results showed that the behavior of the underwater shock waves at the vicinity of the explosives differs greatly from that far from the explosives. Especially, the strength of the underwater shock wave nearby the explosive rapidly decreases due to the effect of the expansion of the gas products.

Abstract:
When preparing a permitted explosive recipe an energy or an explosive heat is considered, which should ensure the detonability of the system and at the same time a power that satisfies the purpose for which it will be used, under the conditions of firedamp hazardous mines. The safety parameters for the explosive charges used in the firedamp hazardous mines are decisive, in order to ensure the safety and health requirements at work together with the efficient performance of the blasting operation. The permitted explosive type emulsion is recommended to be used in underground mines, open pit mines as a special methane explosive and can be used where a coal dust and/or methane explosion hazard exists can be loaded into dry and wet blasting holes and it can be used for mechanical loading. The permitted explosive type emulsion is a Detonator-sensitive explosives that can be reliably initiated in an unconfined state by a No. 8 strength detonator it have safety handling characteristics because of the relatively low sensitivity to friction, shock and impact. Technological changes due to the change of suppliers of certified explosives for civil use for underground use in the firedamp hazardous mines, involve reassessing the safety and efficiency of the loads made with these products, which have not been tested and evaluated for the conditions from the Jiu Valley mines.

Abstract:
In this study, beryllium bronze/steel composite plates were fabricated through explosive welding process using different ratios of explosive. Microstructures of the joint were examined, and then shearing strength, peeling strength, Bending tests and hardness measurements were carried out on the bonded specimens. Experimental studies show that, beryllium bronze and steel could be bonded with a good quality. The interface is wavy texture changing in turns from flat - wavelet - large wave - stable large wave beginning with initiation point. Grains near the interface are elongated parallel to the explosion direction. As the ratio of explosive increase, the amplitude and wavelength of wave are increased, which leads to the increasing of shearing strength and bonging strength. No shearing in the interface is seen from the tensile-shear tests and fracture take place in the low strength material. The bended specimens show that defects such as separation and tearing were not observed. Hardness is increased with increasing explosive ratio and the highest hardness values are obtained near the bonding interface.

Abstract:
Explosion proof structures are designed to be very heavy and non-functional using conventional systems so that they can be resistant to blast effects. As a result, not only the emergence of non-economic structures, but also their operational performance decreases. To effectively mitigate these challenges, a substantial body of research has focused on the development and application of designs and materials specifically engineered to withstand explosive load impacts. In this study, the strength of steel plates under explosives with different energies was tested. Related tests were performed using Ls-Dyna finite element software. An experimental literature was used to calibrate the numerical model. When the results obtained as a result of the calibration were compared with the experimental data, a high level of agreement was obtained. The calibrated numerical model was subjected to burst loads by varying the panel thicknesses and its dynamic responses were simulated. The displacement values were analyzed by placing the explosives equidistant from the panel centers. By comparing the analysis results, explosive energies were compared. The most effective explosive types could be listed according to the amount of change that the evaluated explosives in the same amount caused on the panel surfaces. In line with these studies, information will be gained about what type of steel materials will be used against which type of explosives in areas that need to be protected in urban areas.

Abstract:
The paper presents the main scientific and practical results obtained by the scientists of the Dnipro Polytechnic Institute in 1992-2022. The basis of the proposed physical and mathematical model, taking into account quantum mechanical laws, is the discovered new mechanism of ignition of metal azides by a laser monopulse, due to the structural destabilization of the crystal lattice when heated by radiation of optical microinhomogeneities. Attention is focused on the developed new methods for measuring the sensitivity of explosives and the parameters of the mechanical action of explosion products. The dependence of the sensitivity of explosive compounds on the mode of formation in the volume of the material and the conditions of unloading the samples of the substance was experimentally revealed. Light-sensitive explosive composites have been developed, the sensitivity of which to the action of a laser monopulse is an order of magnitude higher than that of heavy metal azides. The scientific basis for the use of the laser initiation method has been developed to solve the problems of obtaining profiled detonation waves, explosion welding, metal hardening, creation of optical systems for initiating explosive charges, testing material strength and stability of structures subjected to mechanical loading pulses. To improve the safety of blasting operations, experimental samples of the optical initiation system and new means of detonating explosives were created.

Full text
Abstract:
In this investigation, three different explosive materials have been used to improve the properties of titanium grade 2: ammonal, emulsion explosives, and plastic-bonded explosives. In order to establish the influence of explosive hardening on the properties of the treated alloys, tests were conducted, including microhardness testing, microstructure analysis, and tensile and corrosion tests. It has been found that it is possible to achieve a 40% increase in tensile strength using a plastic explosive (PBX) as an explosive material. On the other hand, the impact of the shock wave slightly decreased the corrosion resistance of titanium grade 2. The change in corrosion rate is less than 0.1µm/year, which does not significantly affect the overall corrosion resistance of the material. The reduction in corrosion resistance is probably due to the surface geometry changes as a result of explosive treatment.

Full text
Abstract:
The primary purpose of this thesis was to assess the effect of knee-joint angle on the neuromechanics of maximal and explosive contractions, specifically torque and neuromuscular activation, as well as the influence of isometric resistance training (RT) on these variables and thus joint angle specificity of training adaptations. It was found that electrode location had a pronounced effect on surface electromyography (sEMG) amplitude during maximum isometric voluntary contractions (MVCs) and moderate relationship between subcutaneous tissue thickness and sEMG amplitude (R2=0.31 up to 0.38) was reduced but not consistently removed by maximal M-Wave (MMAX) normalization [up to R2= 0.16 (peak-to-peak) and R2= 0.23 (Area)]. Thus, MMAX peak-to-peak was the better normalization parameter that removed the influence of electrode location and substantially reduced the influence of subcutaneous tissue thickness. Maximal torque-angle relationship presented an inverted U shape with both, agonist (measure by two different techniques) and antagonist neuromuscular activation both differing with knee-joint angle and thus, both likely contributing to the torque-angle relationship. Absolute explosive torque-angle relationship exhibited higher torques at mid-range knee joint angles in a similar manner to maximal strength, whilst the ability to explosively express the available torque (i.e. relative to maximal strength) revealed only subtle differences between joint angles. Agonist neuromuscular activation showed increases from extended to flexed positions during both maximum and explosive contractions (at all time points; ~6% to ~34%) and evoked contractile properties presented opposite patterns with twitch torque increasing (~5% to ~30%) and octet torque decreasing (~2% to ~14%) with knee flexion. Finally, after 4 weeks of RT at a 65° knee-joint angle evidence of joint angle specificity was provided from both within-group (greater gains at 3 angles than others) and between-group evidence (greater gains at 2 angles than others) for maximal strength but not for explosive strength and neuromuscular activation. In summary, this thesis demonstrated: (1) higher strength values at middle knee-joint positions than more flexed and/or extended positions during maximal and explosive contractions; (2) how agonist neuromuscular activation contributes to the beforementioned changes in strength; (3) how muscle contractile properties contribute to the explosive strength across knee-joint angles; and finally (4) that joint angle specificity has a neural basis.

Abstract:
The purpose of this study was to determine the acute effects of stretching and local vibration on flexibility and explosive strength in competitive female gymnasts. Flexibility was measured in the forward-split position and jump characteristics were recorded using a force plate. Analysis included flight time (FT), jump height (JH), peak force (PF), instantaneous forces, and rates of force development (RFDs). Randomly assigned and counterbalanced groups were: simultaneous vibration-stretching (VS) (n=22), stretching-only (n=7), and vibration-only (n=8). VS showed statistically greater measures of flexibility in both the right and left leg, favored and non-favored legs pre- versus post-treatment. Vibration-only group resulted in statistically greater right forward-split flexibility and non-favored leg flexibility. There were no statistical differences in JH, FT, PF, instantaneous forces, or RFDs in the VS, stretching-only, and vibration-only groups' pre- versus post-treatment tests. The conclusion was simultaneous vibration-stretching greatly increased flexibility while not altering explosive strength.

Abstract:
Purpose: Effects of simultaneous vibration-stretching on flexibility and explosive strength in competitive female gymnasts were examined. Methods: Twenty-two female athletes (age = 11.3 ± 2.6 yr; body mass = 35.3 ± 11.6 kg; competitive levels = 3-9) composed the simultaneous vibration-stretching (VS) group, which performed both tests. Flexibility testing control groups were stretching-only (SF) (N = 7) and vibration-only (VF) (N = 8). Explosive strength-control groups were stretching-only (SES) (N = 8) and vibration-only (VES) (N = 7). Vibration (30 Hz, 2-mm displacement) was applied to four sites, four times for 10 s, with 5 s of rest in between. Right and left forward-split (RFS and LFS) flexibility was measured by the distance between the ground and the anterior suprailiac spine. A force plate (sampling rate, 1000 Hz) recorded countermovement and static jump characteristics. Explosive strength variables included flight time, jump height, peak force, instantaneous forces, and rates of force development. Data were analyzed using Bonferroni adjusted paired t-tests. Results: VS had statistically increased flexibility (P) and large effect sizes (d) in both the RFS (P = 1.28 × 10−7, d = 0.67) and LFS (P = 2.35 × 10−7, d = 0.72). VS had statistically different results of favored (FL) (P = 4.67 × 10−8, d= 0.78) and nonfavored (NFL) (P = 7.97 × 10−10, d = 0.65) legs. VF resulted in statistical increases in flexibility and medium d on RFS (P = 6.98 × 10−3, d = 0.25) and statistically increased flexibility on VF NFL flexibility (P = 0.002, d = 0.31). SF had no statistical difference between measures and small d. For explosive strength, there were no statistical differences in variables in the VS, SES, and VES for the pre- versus posttreatment tests. Conclusions: Simultaneous vibration and stretching may greatly increase flexibility while not altering explosive strength.

Abstract:
The purpose of this dissertation was to determine if a periodized strength and conditioning program resulted in long-term adaptations in NCAA Division I women’s volleyball athletes, and if these changes related to the team’s competitive performance. Specifically, this dissertation serves to: 1.) describe the changes in body composition and performance variables of 2 female volleyball athletes over a 4-year collegiate career, 2.) determine the degree and magnitude of change in performance variables after about 1, 2, and 3 years of periodized resistance training, and 3.) infer if volleyball performance characteristics are related to a team’s competitive success. The following are major findings of this dissertation. 1.) Positive changes in vertical jump height, strength, and explosiveness may be possible throughout 4 years of collegiate volleyball training even with increased body mass and percent body fat. Moreover, impaired ability to perform heavy lower-body resistance training exercises due to chronic injury negatively impacts long-term physical performance adaptations over 4 years. 2.) A combination of traditional resistance training exercises and weightlifting variations at various loads, in addition to volleyball practice, appear to be effective at increasing maximal strength by 44% and vertical jump height by 20%-30% in NCAA Division I women’s volleyball athletes after about two and half years of training. Furthermore, these characteristics can be improved in the absence of additional plyometric training outside of normal volleyball-specific practice. 3.) A rating percentage index RPI ranking ratio and unweighted match score ratio appear to be better predictors of overall team competitive season success than a weighted match score ratio. On the contrary, a weighted match score ratio may be better for determining an association between team match performance and volleyball-specific fitness. A considerable amount of research is needed to develop a volleyball-specific performance index that best quantifies team performance and whether or not a measurable association exists between improved fitness characteristics and increased overall team competitive success. The findings of this dissertation provide evidence that analyzing and monitoring volleyball-related performance variables over time can assist the sport performance group in making training based decisions as well as promote the successful development of an athlete.

Abstract:
PURPOSE: The purpose of the study was to examine the relationship between bat swing velocity and lower extremity strength and power in NCAA Division-I softball athletes. METHODS: Twenty-nine softball athletes (age = 19.8 ± 1.3 years, height = 167.9 ± 6.8 cm, mass = 76.4 ± 18.1 kg) participated in the study. Athletes were tested on unloaded and loaded (20kg) squat and countermovement jump peak force, peak power, and jump height performed on a force platform sampling at 1000Hz. During practice, athletes were tested on swing velocity using a timing gate system. Pearson-product moment zero-order correlations were calculated between bat swing velocity and lower extremity strength and power. Statistical significance was set at p≤0.05. RESULTS: Moderate to strong relationships were observed between swing velocity and peak force at all conditions: SJ 0kg (r= 0.51, p= 0.005), SJ 20kg (r= 0.50, p= 0.006), CMJ 0kg (r= 0.44, p= 0.016), CMJ 20kg (r= 0.43, p= 0.022). Additionally, relationships were observed between swing velocity and peak power at all conditions: SJ 0kg (r= 0.45, p= 0.015), SJ 20kg (r= 0.40, p= 0.031), CMJ 0kg (r= 0.53, p= 0.003), CMJ 20kg (r= 0.45, p= 0.015). No statistically significant relationships were observed between swing velocity and jump height. CONCLUSIONS: Swing velocity was related to lower extremity force and power variables. Considering the known effects of strength training on lower extremity strength and power production, these results provide background for inclusion of lower extremity strength training for the development of swing velocity in NCAA Division-I softball athletes.

Massey, Garry J. "Muscle-tendon unit morphology, architecture and stiffness in relation to strength and responses to strength training." Thesis, Loughborough University, 2017. https://dspace.lboro.ac.uk/2134/24712.

Full text
Abstract:
This thesis examined the change in skeletal muscle architecture with contractile force production, the relationship of architecture with muscle strength parameters and if muscle tendinous tissue stiffness determines in vivo explosive strength (i.e. rate of torque development, RTD). Muscle and tendinous tissue adaptations to contrasting strength training regimes, and the potential capacity of these tissues to adapt following chronic strength training were also explored. Quadriceps femoris fascicle length (FL) decreased, while the pennation angle (PA) increased in a curvi-linearly manner from rest to maximal voluntary contraction (MVC) torque. Consequently, effective physiological cross-sectional area (effPCSA) during MVC was 27% greater than at rest, although effPCSA measured at rest and during MVC had similar correlations to maximal strength. In the earliest phase of contraction, FL, but not PA, was negatively related (R2=0.187) to voluntary RTD. Neither FL nor PA was related to maximal isometric or dynamic strength. Muscle-tendon unit (MTU) and patellar tendon (PT) stiffness were unrelated to voluntary and evoked RTD. Relative PT stiffness was also unrelated to relative RTD, although relative MTU stiffness was related to voluntary RTD (25-55%MVT, R2≤0.188) and evoked RTD (5-50%MVT, R2≤0.194). MTU stiffness increased after sustained-contraction (SCT, +21%), though not explosive-contraction strength training (ECT). PT stiffness increased similarly after ECT (+20%) and SCT (+16%), yet neither induced tendon hypertrophy. SCT produced modest muscle (+8%) and aponeurosis (+7%) hypertrophy. Chronic strength trained (CST: >3 years) males had substantially greater muscle and aponeurosis size, but similar tendon size as untrained controls (UNT) and short-term (12 weeks) strength trained (STT) individuals. Between these groups, at the highest common force, MTU stiffness was indifferent, while PT stiffness was similarly greater in STT and CST than UNT. These results suggest FL and PA have little influence on muscle strength and tendon stiffness has no influence on RTD. Maximum strength negated any qualitative influence of MTU stiffness on in vivo RTD. Component MTU tissues (muscle-aponeurosis vs. external tendon) adapt differentially depending on the strength training regime. Specifically, free tendon appeared to adapt to high magnitude loading, while loading duration is also an important stimulus for the muscle-aponeurosis. However, chronic strength training was not concordant with greater higher force MTU stiffness, and does not further increase higher force PT stiffness beyond the adaptations that occur after 12 weeks of strength training. Finally, no evidence was found for tendon hypertrophy in response to strength training.

Abstract:
AbstractJapan is located in the international seismic zone, and is also a resource intensive country. It has unique features in the research and application of ultra-high performance concrete materials. The paper analyzes and summarizes the engineering application cases of concrete strength grade above 150 N/mm2, including structural system, mix design, production process, strength grade, etc. Silica fume composite cement, with strict calculation of sand and stone gradation, improves the compactness beyond the conventional concrete; The super high performance water reducing agent can greatly reduce the water cement ratio and improve the working performance, especially the expansion degree; Organic fiber and steel fiber are especially important in fire resistance, explosion resistance and ductility. Ultra-high performance concrete could improve the seismic performance of building structures and the utilization rate of building area, and new materials could provide more choices for design and engineering application.

Full text
Abstract:
In this work explosive line and spot welding were used for the bonding of light-weight metal sheets. Materials involved are aluminum alloys 5052-O, 6061-T6, and 7075-T6, a magnesium alloy AZ31B-O and a commercially pure titanium (TP270C). Plates of similar and dissimilar metal combinations are explosion welded over a small overlapping area. The strength of the welds was measured using shear strength tests and the metal interface was analyzed using optical microscopy. The shear strength of the welds have been tested and appeared to high shearing strength. Explosive line and spot welding show a high strength to explosive mass ratio, making it a good candidate to be scaled up and used in commercial applications.

Abstract:
One of promising directions in conducting sparing highly mechanized blasting operations in open-pit mining may be the use of low-density emulsion explosives sensitized with light porous granules made of low-strength material (for example, granules of polystyrene foam). Experimentally, it was possible to show that such explosives allow mechanized charging into downward hole wells and allow forming a borehole charge that is virtually not subject to shrinkage at a height of up to 40 m. Low explosive densities make it possible to effectively use solid column charges for gentle blasting which, in turn, provides a high degree of mechanization of charging operations.

Abstract:
Explosion will generate electromagnetic radiation, the time domain waveform and spectrum generated from different types of explosives are different. For researching the characteristics of the electromagnetic radiation in process of explosion, the electromagnetic radiation signals and the images of the explosion process of typical single-compound explosives TNT and RDX are measured by wide band electromagnetic radiation signal measuring devices and high-speed photography. The experimental results show that the peak time of electromagnetic signals of TNT and RDX are significantly delayed compared with the initiation time of the detonation. The delay time of the peak signal of TNT explosion electromagnetic radiation is 55.07μs, and the delay time of RDX is 68.40μs. At 5m from the detonation center, the peak signal electric field strength of TNT and RDX explosion electromagnetic radiation is 1.92V/m. After the initial discharge interference signals have been removed, the electromagnetic pulse signals are analyzed by Fast Fourier Transform, it is shown that during explosion, the frequency of electromagnetic radiation is within 100MHz, and the frequency spectrums of electromagnetic radiation signals of different explosives are different.

Abstract:
When explosive material is ignited, a detonation wave is generated causing a chemical reaction to take place. This chemical reaction results in the creation of a shockwave in the air surrounding the explosive material. The properties of this shockwave are dependent upon many different variables including but not limited to the type of explosive material used, the amount of material used, the surrounding fluid and the distance that the shockwave travels from the point of ignition. One variable that is not often considered is how the topology of the explosive material may affect the properties of a shockwave. If all other properties are held constant, the shockwave created by a spherical explosive charge will have different properties from those created by a cylindrical or cubical charge. This work uniquely applies an explicit finite element approach to simulate different shapes of explosives and the effects of explosive surface topology on the ensuing shockwaves. In order to fully observe these varying shockwaves, a target wall was included in the simulations. The propagating shockwaves damage the wall on impact, while creating a series of reflective shock- and strain-waves. By thoroughly examining the damaged portions of the target wall in conjunction with wave propagation patterns, it is possible to study the strength of the shockwave and the mechanism by which the reflective waves are created. Through these investigations, shockwave pressure, velocity, patterns and shapes, as well as damage sustained by the wall will be considered. The paper will conclude how shockwave properties are influenced by the original topology of the explosive mass.

Full text
Abstract:
Abstract Explosive containment vessels (ECVs), such as those utilized to contain the detonation products of explosives during bomb/munition disposal or containment of experiments on explosive devices, are required to be fabricated from high-integrity materials to ensure the safety of people and/or property in the vicinity of the vessel. Candidate materials for ECV construction are desired to exhibit high strength and high toughness to prevent ductile exhaustion and/or brittle failure induced by impulsive loading; a non-trivial requirement given that, generally, materials exhibit poorer toughness with increasing strength. Additionally, vessel manufacturability (e.g. weldability and component thickness) also needs also to be considered when selecting materials for ECVs. Los Alamos National Laboratory has had success using both A723 and HSLA-100 steel alloys for ECV applications. The present article provides a background on these two alloys and compares them from the perspectives mentioned above. A723 is better suited for thick-section and non-welded applications, whereas HSLA-100 is better suited for thinner (< ∼10 cm) vessel components but also supports welding without post-weld heat treatment. Discussion is included regarding how the effects from the alloy compositions of these two steels enables them to perform in complementary applications. This discussion is extended to current alloy development for ECVs which seeks to improve performance and manufacturability.

Abstract:
The aim of the study was to detect the current level of explosive strength of lower limbs. Results were compared with the best individual personal performance which is evaluated through FINA points. 10 male and 14 female junior representatives in swimming (n=24; height = 178.7 ± 7.59 cm; weight = 67.5 ± 7.76 kg) and 10 male and 8 female senior rep-resentatives in swimming (n=18; height = 179.8 ± 5.54 cm; weight = 72.6 ± 8.32) from the Slovak Republic participated in testing. The explosive strength of lower limbs was meas-ured by standing broad jumps and by the diagnostic device Myotest where CMJ and SJ tests were used. The results were compared by Pearson correlation coeficient with the best point performance of a particular proband. The average height of the junior repre-sentatives in the SJ test was 33.0 cm and of the senior representatives was 40.9 cm. The average height of the junior representatives in the CMJ test was 36.0 cm and the value of the senior representatives was 45.9 cm. The average value of junior representatives in the standing broad jump test was 220.0 cm and in senior representatives was 269.3 cm. Senior representatives achieved better results in all tests. The average point performance in junior representatives was 708.0 points and in senior representatives was 761.7 points. Percen-tual difference between the groups was detected in tests at values from 18.1% to 21.6% and the difference in FINA points was 7.1%. Pearson correlation coeficient showed high and medium values on statistical significance of 1% between tests of explosive strength, although, it showed the low values between the explosive strength tests and value of FINA points. The explosive strength of the lower limbs is one of the factors of sports performance that affect swimming performance. However, its level of impact needs to be verified by fur-ther research.

Abstract:
The Indonesian government plans to sue PTTEP Australasia, PTTEP, and PTT for the 2009 Montara oil spill, seeking 27.4 trillion rupiahs (USD 1.85 billion) in damages. The explosion on an oil rig in the Montara field, operated by PTTEP AA, caused one of Australia's worst oil disasters, spilling 23.5 million liters of oil into the Timor Sea for 74 days and impacting the Indonesian coast. The government initially filed a lawsuit but withdrew it to strengthen their claim and correct the defendants' names. Despite a settlement with Indonesian farmers, the government seeks additional compensation for environmental damage. The case has drawn international attention due to its cross-border implications and significant environmental impact.
