Abstract

The response process of clamped square plates subjected to close-range explosion was divided into three stages. On the basis of a certain simplified conditions, an approximate calculation method of deflection of clamped square plates subjected to close-range explosion was given based on principle of momentum conservation. Based on the numerical simulation method, the influence of water on the plate deflection was disscussed. The results show that, with the effections of water, the deflections of plates become smaller and the deformations of plates exhibit significant local effect. Forward, the effect of charge shape and charge distance on deflections of water back plate were also studied by simulation methord. Comparison results show that the approximate calculation results is in good assistance with simulation's when the charge distance is small.
