| Abstract: | A simple formula is developed here by using Jones-Sawczuk's equation in order to estimate the permanent transverse deflections of rectangular plate which is subjected to & blast loading. Maximal permanent transverse deformation of fully clamped square plate acted by blast loading is calculated by using the formula proposed in this paper and a square yield curve. It is observed that reasonable agreement between the theoretical predictions and the experimental results has been obtained. |
