The approach is based on the assumption that necking mode can be modeled under plane stress conditions and shear localization can be modeled under plane strain conditions.
这种方法是以一种假设为基础的,即可以在平面应力条件下仿照缩颈模式和在平面应变条件下仿照剪切定位,材料是用弹、粘塑性物质构成的仿制品。
Presumably, it is due to their different critical values of the ratio of slip plane hardening rate to current tensile stress for shear localization.
这可能是由于它们产生剪切形变局部化的滑移面硬化率对瞬时拉伸应力的临界比值不同之故。
Presumably it is due to their different critical values of the ratio of slip plane hardening rate to current tensile stress for shear localization.
这可能是由于在不同状态时产生剪切形变局部化的滑移面硬化率对瞬时拉应力的临界比值不同之故。
