FINITE DEFLECTIONS OF A RIGID VISCOPLASTIC STRAIN-HARDENING ANNULAR PLATE LOADED IMPULSIVELY

Abstract

A relatively simple analytical treatment of the behavior of a rigid- plastic annular plate subjected to an initial linear impulsive velocity profile is presented. The influence of finite-deflections has been included in addition to strain-hardening and strain-rate sensitivity of the plate material. It is shown, for deflections up to the order of twice the plate thickness, that strain-hardening is unimportant, strain-rate sensitivity has somewhat more effect, while membrane forces play a dominant role in reducing the permanent deflections.
