摘要
详细描述了依据损伤原理建立的连续损伤模型,并对该模型进行了改进。在LS DYNA程序用户自定义材料模型中加入改进的连续损伤模型,并对弹体侵彻钢筋混凝土的穿孔过程进行了数值模拟,其结果与实验结果相吻合,模型可以用于钢筋混凝土的动态破坏预报。
Based on the continuum damage description, a continuum damage model was established and modified. The modified model was implemented in transient dynamic explicit finite element code LS-DYNA3D and used to simulate the reinforced concrete perforation. The numerical simulation results show a good agreement with the measured data. The model is capable of to predict the behavior of the dynamic reinforced concrete.
