ductile fracture criteria的意思|示意

At present, some ductile fracture criteria are applied only to predict the forming limit in stamping forming of simple axisymmetric part.

目前已提出的韧性断裂准则预测板料成形极限，只在简单轴对称件中得到应用。

This paper predicted the forming limit of sheet metals by using the mechanical property parameters of materials and combining the ductile fracture criteria with finite element simulation.

本文提出利用材料的力学性能参数，采用数值模拟与韧性断裂准则相结合的方法预测板材的成形极限。
