on deformation and unstable snap-back for shear band and elastic rock system WANG Xue-bin(王学滨) (Department of Mechanics and Engineering Sciences, Liaoning Technical University, Fuxin 123000, China)  ... shear strain and deformation in shear band and on the stability of direct shear rock specimen were investigated[7]. In theoretical analyses by WANG et al[3-7], shear band was treated as a one......
Quantitative calculation of local shear deformation in adiabatic shear band for Ti-6Al-4V WANG Xue-bin(王学滨) Department of Mechanics and Engineering Science, Liaoning Technical University, Fuxin..., to calculate the distribution of local total shear deformation(LTSD) in adiabatic shear band(ASB). The predicted LTSDs at different flow shear stresses were compared with experimental measurements. J-C model......

; Abstract: A recently proposed model coupling with the solid-fluid of the saturated sand was utilized to study the deformation band. Based on the critical... affects the onset and development of the deformation band, and it obviously increases around the localization-prone regions with the direction toward the outer side of the normal of the shear band......

Formation of adiabatic shear band and deformation mechanisms during warm compression of Ti–6Al–4V alloyJiao Luo,Lin-Feng Wang,Miao-Quan Li,Chang-Jian Ge,Xiao-Xiao Ma,Yong-Ting YangSchool of Materials...(SEM). And the deformation mechanisms within the shear band were discussed thoroughly with the help of transmission electron microscopy(TEM). There is a critical strain for the formation of ASB during......
镁合金热变形下变形带的形貌和晶体学特征杨续跃1,2,姜育培1(1.湖南省长沙市中南大学材料科学与工程学院2.湖南省长沙市中南大学教育部,重点实验室有色金属材料科学与工程)摘 要:对不同温度单向压缩下AZ31镁合金不均匀形变组织的形貌和晶体学特征进行了研究.结果显示:形变组织具有很强的温度和应变敏感性;250℃时,晶粒内在变形初期出现大量的{1012}拉伸孪晶和少数{1011}压缩孪晶,随着应变量的加大,拉伸孪晶因相同取向孪晶的合并而急剧减少,而压缩孪晶明显变粗,数量也有所增加;300℃以上时,非基面滑移被激活后......

towards the right continually. For the sake of calculation, it is assumed that the shear deformation only occurs in the horizontal direction. The total length of shear band is L1+L2. The thickness of shear.... For simplicity, we let τf =0. Due to the non-uniform deformation of specimen beyond the onset of shear band or strain localization, the measured stress-strain curve is not a purely mechanical......
