用新研制成的DE36平台钢制成的轴对称和平面应变试样,进一步考察了临界穴扩张比V_(Gi)准则的适用性。实验和大应变有限元理论计算结果表明,V_(Gi)准则适用于所研究材料。本文还叙述了一种将V_(Gi)准则运用于实际构件上的方法。
Axial symmetry and plane strain specimens made of newly developed DE36 steel were further investigated for applicability of the critical cavity expansion ratio V Gi. The experimental and large-strain FEM calculations show that the V_ (Gi) criterion is suitable for the studied materials. This paper also describes a method of applying V_ (Gi) criteria to real components.
