Abstract
An approximate theoretical procedure is developed herein in order to estimate the permanent transverse deflections of beams and arbitrarily shaped plates which are subjected to large dynamic loads. The influence of finite-deflections or geometry changes is retained in the analysis but elastic effects are disregarded. The particular case of a fully clamped rectangular plate acted on by a uniformly distributed dynamic pressure pulse is studied in some detail. It is observed that reasonable agreement between the theoretical predictions and the experimental results has been obtained for beams (β = 0) and rectangular plates (β = 0.593) which were made from a strain-rate insensitive material.
