In this paper, the plastic deformation of clamped rectangular steel plates is investigated both experimentally and numerically using gases mixture detonation approach. In this series of experimental tests, the steel plates with various thicknesses were deformed under shock wave effect which had been caused by high velocity rate explosion. Also, the pressure of gases mixture detonation was measured after detonation by piezoelectric pressure transducer. The experimental results related to effect of parameter such as the percentage of gas mixture, plate thickness and boundary condition on longitudinal, transverse and diagonal strain distribution were presented. The numerical simulation is carried out using the finite element analysis software ABAQUS/Explicit. To validate the numerical simulation, the obtained results of simulation were compared with experimental ones. This comparison demonstrates that the numerical results have satisfying compatibility with experimental results. In general, all data is in the reliable range. Hence, utilizing the mentioned numerical model is appropriate for predicting the deformation profile and also the midpoint deflection of rectangular steel plate.
