摘要：
A step-by-step dynamic finite element analysis is presented in which a provision is made for a three-dimensional isoparametric element existing in the target metal plate. On the basis of this analysis, the computer program OBAID has been modified for dynamic loading due to impinging shot. The target material is considered to be elastoplastic and the analysis allows for strain and work hardening. The problem is envisaged to embrace a process of multiple indentations which cover the surface of the target progressively, thus allowing for shakedown of each spot due to repeated impact and also saturation due to complete surface coverage. © 1990.
