| 摘 要： | 利用ABAQUS/Explicit模块所提供的材料本构接口VUMAT,将一种含损伤热塑性本构方程和微空洞延性损伤准则引入其中,以圆柱壳在外爆载荷下破坏问题为例,进行了数值模拟,将壳体破裂时的一些参数与实验进行了比较,包括破裂时间与平均环向应变,结果基本相符,说明所采用的方法可行有效.

| Abstract: | A kind of thermoplasticity constitutive equation and void ductile damage criteria with temperature softness effect were imported to ABAQUS/Explicit with its material interface(VUMAT).Based on this,the cylindrical shell damage under explosive load was simulated.The damage parameters including damage time and circumferential strain were compared with that of experiments.They matched well and the way is feasible and effective. |
