| Abstract: | 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. |
