plastic strain limit

基本解释

In sheet metal forming processes under tensile stresses, the plastic strain limit can be evaluated. Much experimental work can be saved.
在板料成形中，拉应力下颈缩失稳的临界应变值可以定出。
By analyzing the real stress— strain curve with theory of plastic instability and using this testing method, another form of the forming limit diagram has been found.
在利用共稳理论对实际应力应变曲线进行分析的同时，得出了求作板材成形极限图的新方法。
Plastic limit load of viscoplastic thick-walled cylinder and spherical shell subjected to internal pressure is investigated analytically using a strain gradient plasticity theory.
基于应变梯度塑性理论，分析了内压作用下厚壁圆筒和球壳的塑性极限荷载。
