本文提出了一种近似的理论计算方法，用以估算梁和任意形状板在大动载荷作用下的永久横向挠度。分析中保留了有限挠度或几何形状变化的影响，但忽略了弹性效应。本文详细研究了完全固支矩形板受均布动压脉冲作用的特殊情况。对于由应变率不敏感材料制成的梁（β= 0）和矩形板（β= 0.593），理论预测与实验结果符合较好。
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.
