Trans. Nonferrous Met. Soc. China 27(2017) 1608-1617 Dynamic mechanical properties and instability behavior of layered backfill under intermediate strain rates Yun-hai ZHANG, Xin-min WANG, Chong WEI... degree of lower strength part of LBS is generally higher than that of higher strength part. A revised brittle fracture criterion based on the Stenerding-Lehnigk criterion is applied to analyzing......
Preliminary Study to Identify Criterion for Quench Crack Prevention by Computer Simulation Fumiaki Ikuta1,Michiharu NARAZAKI2,Kyozo Arimoto3,Shigeyuki Tamura4,Takashi Horino1,Yoshio Mikita5...:A criterion for preventing quench cracks has not been established although much research has been conducted in this field. A few predictions of cracking have been recently reported using simulated......
University, Changsha 410075, China)Abstract:On the basis of upper bound theorem, non-associated flow rule and non-linear failure criterion were considered together. The modified shear strength... criterion, pore water pressure, surface loads and buried depth, on the stability of shallow tunnel were studied. In order to validate the effectiveness of the proposed approach, the solutions......
, the crack starts from a neutral plane. However, fracture morphology of rock beams under disturbance load is irregular, cracking position of fractures deviates from a neutral plane. Delayed instability of rock beam occurs for some time under constant disturbance load. When disturbance load is beyond a certain range, suddenly instability of occurs rock beam in a certain time. The results show......
bias temperature instability (NBTI) and positive bias temperature instability (PBTI) on power gated static random access memory (SRAM). The experiment results show that PBTI has significant influence... that the proposed model has a reduction of 3.85% for estimation of the SNM degradation after 106 s working time compared with previous work.Key words:negative bias temperature instability (NBTI); positive bias......
Improved similarity criterion for seepage erosion using mesoscopic coupled PFC–CFD modelNI Xiao-dong(倪小东), WANG Yuan(王媛), CHEN Ke(陈珂), ZHAO Shuai-long(赵帅龙) (Key Laboratory of Ministry of Education... seepage deformation in model tests may deviate from similarity was first discussed in this work. Then, the similarity criterion for seepage deformation in porous media was improved based on the extended......
