| 摘 要： | 自锻破片装药(简称SFF)是从聚能破甲装药派生出来的一种新的反坦克装药结构。描述SFF的形成过程,我们采用二维轴对称弹性-理想塑性-流体力学方程组。基本数值方法采用M.L.Wilkins的迴路积分法和Legrange四边形网格。数值模拟得到的SFF完整的形成过程和试验中x射线高速摄影照片基本相符。数值模拟中的若干方法简化了计算,节省了机时。

| Abstract: | The process of forming of Self Forging Fragment (SFF for short) is a very complicated problem of explosion. Because of SFF is axisymmetric, 2-d imentional elastic-plastic mechnical equations are used to discribe this process. In solving these equations, we use integral definitions of the partial derivatives by M.L. Wilkins,and Lagrange quadrilateral grid.The shape of the SFF obtained from our 2-dimensional numerical simulation compares fairly with that in the high speed x-ray photogragh of the actural experimental process. |
