Experimental and Numerical Investigation into Plastic Deformation of Rectangular Plates Subjected to Hydrodynamic Loading

Nowadays due to increasing industrial utilization of shock waves, it became popular to use analytical, numerical modeling and experimental tests to evaluate effect of shock waves on metal deformation. To explain this effect on metal properties, current paper considers both experimental and numerical plastic deformation of clamped rectangular steel and aluminum plates, under hydrodynamic loading of drop hammer system. To validate the explicit finite element simulation by solver ABAQUS, experimental test on rectangular plates with various thickness and energy levels have been performed. Obtained results by the numerical simulation are in a very good agreement with those in the experimental tests. Hence, it is desirable to utilize the numerical modeling to predict mid-point deflection of rectangular plate under hydrodynamic loading.
