The purpose of this work is to develop analyses for the elastoplastic and large-displacement response of thin plates to blast or explosive loading. Applications lie in the fields of military structures and explosive forming. Analyses which consider the elasto-plastic and large-displacement responses both separately and in combination are presented. During the development of the computer programs it proved desirable to investigate in some detail, the quasi-static elasto-plastic response and the plate-bending eigenvalue analysis of thin plates, and separate sections are included on these topics. The work is based on the finite element method and employs hybrid Pian elements. Modified author abstract
