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，拉應力下頸縮失穩的臨界應變值可以定出。
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.
在利用共穩理論對實際應力應變曲線進行分析的同時，得出了求作板材成形極限圖的新方法。
Plastic limit load of viscoplastic thick-walled cylinder and spherical shell subjected to internal pressure is investigated analytically using a strain gradient plasticity theory.
基於應變梯度塑性理論，分析了內壓作用下厚壁圓筒和球殼的塑性極限荷載。
