摘要: 利用单个立方体单元压缩和拉伸数值模拟揭示了HJC混凝土模型的抗压,抗拉和损伤特性，将该模型用于模拟Hanchak侵彻试验，采用最大主应变，等效塑性应变和最大拉静水力三种失效模式后得到的残余弹速和靶板破坏现象与试验结果对比后，最大主应变和拉静水失效得到的弹体残余速度误差比等效塑性应变失效要小，等效塑性应变失效得到的靶板表面破坏现象与实验结果也相差较大。

Abstract: The compression, tensile and damage characteristics of HJC concrete was demonstrated by single brick element compression and tensile simulation, the model was applied to simulate Hanchak perforation experiment，by setting maximal principal strain, equivalent plastic strain and maximal tensile hydrostatic pressure failure index in the simulation, residual velocity and slab failure phenomenon was compared with those from experiment results, both maximal principal strain failure index and maximal tensile hydrostatic pressure failure index obtain good agreement with projectile residual velocity in the experiment than equivalent plastic strain failure index. In addition, equivalent plastic strain failure index show less reasonable spall phenonmon on the surface of slab.
