摘要
讨论了连续介质力学守恒方程的有限元离散方法,针对高速碰撞的物理特点,提出了数值计算中所应重视的问题及其有效的解决办法。文中给出的典型算例说明本方法对各类高速碰撞问题的数值模拟计算是十分有用和成功的。
The finite element discretization of conservative equations in continuum mechanics is discussed in this paper. Several problems which should be taken into account in numerical study of hypervelocity impact are stressed and the effective measures to solve them are also described in the paper. Typical examples are given to show that the program which is build up by this method is very useful and successful in numerical simulations of hypervelocity impact.
