VISCOPLASTIC BEHAVIOR OF PLATES WITH FINITE DEFLECTIONS

A theoretical investigation is developed herein in order to estimate the permanent transverse deflections of rectangular plates when subjected to large dynamic loads. The influence of finite deflections or geometry changes and of strain-rate sensitivity is retained in the analysis but elastic effects are disregarded. The particular case of a fully clamped plate acted on by a uniformly distributed pressure pulse is studied in detail. It is observed that good agreement between the theoretical predictions and experimental results has been obtained for rectangular plates made from strain-rate sensitive material.
