中文摘要：
将CE／SE方法推广到二维固体流体弹塑性问题的数值计算，同时结合杂交粒子水平集方法追踪物质界面和合适的边界条件，提出一套完整的二维Euler型流体弹塑性计算方案．通过长钨杆侵彻装甲钢实验的数值模拟，对方法的精度和有效性进行验证．
英文摘要：
We extend the CE/SE scheme and present a complete Eulerian approach for two-dimensional （plane strain and axisymmetry） elastic-plastic flows with solid features. Eulerian governing equations are adopted and solved on a fixed Cartesian grid. Johnson-Cook constituted equations and Mie-Grüneisen equation of state are used to describe materials. A hybrid particle level set method is used to trace interfaces of materials. Two types of boundary condition are presented in tracking interface. The penetration of a steel target by a WHA long rod is simulated and the computational results are carefully compared with those in other literatures.
