An automated dynamic finite element analysis is presented in which provision is made for three-dimensional isoparametric element existing in the target metal plate. A steel plate with nine layers is chosen. The plate is idealised using 20 noded isoparametric elements and is subjected to steel shots with varying velocities. On the basis of this analysis, the computer program has been developed to dynamic loading due to impinging shot. The analysis presented herein includes facilities for loading and unloading phenomena and automatic production of residual stresses. The residual stresses from the analysis are in a good agreement with those obtained from others.
