摘要 对混凝土、沙岩两种介质[1 ,2 ] 给出了带有损伤变量的本构方程及参数 ,将这些关系编入二维弹塑性有限元程序 (LTZ 2D) ,然后利用程序数值模拟了射弹、动能弹对混凝土、沙岩靶的侵彻 。 The constitutive model and its parameters of concrete and rock with damaging variables are given referring to [1,2],and coded into a 2-D elastic-plastic finite element program named LTZ-2D.With this program,the problem of projectile and kinetic bullet penetrating concrete and rock targets is numerically simulated.The results of simulation are compared with those of experiments.
