Impulsive Loading of Rectangular Plates with Finite Plastic Deformations

Abstract

This paper is concerned with the responses of inelastic rectangular plates to impulsive loadings. The effects of strain hardening and strain rate sensitivity of the material are taken into consideration in this analysis. A variational principle in dynamics of inelastic bodies subject to finite deformation is used to determine the deformation process of the plate. A sandwich plate idealization is employed. The accuracy of the numerical solution is evaluated by comparing it with the existing analytical and experimental results. The results indicate that this method is adequate for determining the dynamic behavior of inelastic rectangular plates at relatively large deformations.
