CRACK PROPAGATION IN POLYCRYSTALLINE ELASTIC-VISCOPLASTIC MATERIALS USING COHESIVE ZONE MODELS被引量：1
《Applied Mathematics and Mechanics(English Edition)》2006年第4期509-518,共10页吴艳青 张克实 
Project supported by the National Natural Science Foundation of China (No.50371042) the Post Doctoral Science Foundation of China (No.20040350031)
Cohesive zone model was used to simulate two-dimensional plane strain crack propagation at the grain level model including grain boundary zones. Simulated results show that the original crack-tip may not be separated ...

长期以来,合金成分-温度相图的液相线(TL)以上区域被视为均一的液相区,即传统平衡热力学理论所指的均匀液体。关于液体结构和性质对温度的关系,传统理论一直认为从TL到液-气临界点为连续渐变;然而,近年来的研究却观察到了不同于上述传...
