该模型主要应用于高应变率、大变形下的混凝土模拟。在DYNA中H-J-C模型的定义方式为：*MAT_JOHNSON_HOLMGUIST_CONCRETE，材料编号为111。 H-J-C模型综合考虑了大应变、高应变率、高压效应，其等效屈服强度是压力、应变率及损伤的函数，而压力是体积应变（包括永久压垮状态）的函数，损伤积累是塑性体积应变、等效塑性应变及压力的函数。 下面是一个例子： $ $H-J-C

爬格子的人为什么添加拉伸破坏准则后，看不到结构的拉伸破坏，只是看到单元被拉长，但是不能删除单元呢？相反取掉拉伸破坏准则，则能看到断裂现象；如果定义拉伸不定义压缩破坏，则看到单元被拉长，但是没有提示单元被删除的信息！不知道是什么原因呢？同时定义了拉伸以后察看拉伸单元的信息，其应力值仍然是Fc，而不是T的值，由此可见，mat-111在960中并不完善，欢迎不吝指教！lieut2003
