Abstract:

Based on the elastic dynamic analysis of thick – wall cylinder under impact load with dynamic linear and non-linear finite element method(FEM), the change rules of stress, displacement, velocity of thick-wall cylinder were presented under impact load, the result of FEM is coincident with the analytical result. So we can conclude that the setup of the mechanic model is feasible, the calculating result is believable, and the result can be used for the elastic design of thick-wall cylinder under impact load, it also lays the foundation of elasto-plastical analysis of thick-wall cylinder under impact load.

Key words: finite element, stress analysis, heavy wall pipe
