چکیده مقاله
In this paper, the effect of strain rate sensitivity of material in the case of a fully clamped circular plate has been discussed In order to do so, a simple mass and wire model is assumed Then using Cowper Symonds constitutive relation and Perrone Bhadra Simplifications, the mean strain rate of such a plate has been calculated Experiments have been conducted on 5010 Aluminium and St37 Plates which were subjected to underwater explosion According to the experimental results, the dynamic collapse pressure of the plate is figured Finally, the dynamic to static collapse pressure, which is a way to observe the strain rate sensitivity of a material, is determined
