cards were added. The effects of strain to interplanar distance and crystal size of the explosive were studied. The results show that grain size of plastic bonded explosive is decreasing...X-Ray Measurement of Residual Stress in Plastic Bonded Explosives Zhang Weibin1,Chen Jinghua1,Wei Xingwen1,Zhao Beijun1,Zhu Shifu1,Yong Zhihua1 (1.Department of Material Science and Engineering......
modulus and plastic deformation. The tensile tests were performed to investigate the influence of plastic deformation on elastic modulus at low strain rate. Two different aluminum sheets were used... of the elastic modulus versus plastic strain was taken into account. YAN and XU[6] addressed the effect of non-linear elastic unloading on spring-back prediction of V-shape bend. LI et al[7] discussed......

Effect of plastic strain and forming temperature on magnetic properties of low-carbon steelFan Zeng1,Xue-jiao Bai1,Cheng-liang Hu1,2,Zhen Zhao1,21. Institute of Forming Technology and Equipment... flux density showed a sharp decrease at the start of plastic deformation, but as the strain increased, the decreasing trend gradually reached a constant value. The decrease was much larger for cold......
, according to the softening elastic-plastic model based on the conventional triaxial compression tests to simulate the strain softening soils. The small strain in the elastic zone and large stain in the plastic zone and the rational yield function for the strain softening phase stage, the analytical solutions to the compaction grouting pressure were presented. The results indicate reasonable......
Plastic deformation mechanisms of AZ31 magnesium alloy under high strain rate compression YANG Yong-biao(杨勇彪)1, 2, WANG Fu-chi(王富耻)1, TAN Cheng-wen(谭成文)1, WU Yuan-yuan(吴园园)1, CAI Hong-nian(才鸿年)1... attributed to the difficulty in activating a sufficient number of independent slip and twinning systems. During deformation, plastic strain is accommodated mostly by basal slip and tension twinning......
