调用ABAQUS内置JH2模型模拟冲击损伤-ABAQUS例子

The JHB and JH-2 models are available as built-in user materials for Abaqus (i.e., via VUMAT subroutines that are built-in). 

These built-in materials are invoked by using material names starting with ABQ_JHB and ABQ_JH2, respectively.

Johnson-Holmquist model描述

 uses the JH-2 model. The JH-2 model assumes that the damage variable increases progressively with plastic deformation.  The material parameters used for the JH-2 model are listed in Table 2.1.18–4. The JH-2 model similarly consists of three components.
