DYNAMIC IMPACT SIMULATION FOR SHOT TARGET INTERACTION - PLASTICITY RESIDUAL-STRESSES AND RESPONSES

This paper gives an analysis of a dynamic shot impact on a steel target by using a three-dimensional dynamic finite element analysis in which provision is made for the simulation of impact loads, plasticity and residual stress. An assessment is made of the residual stress and plasticity. A computer program, OBAID, has been used to obtain the results. The residual stresses and plasticity zones have been plotted in three dimensions. The history of these diagrams is self-explanatory.
