An Analytical and Numerical Investigation on the Dynamic Responses of Steel Plates Considering the Blast Loads

This study involves an analytical approach to investigate the dynamic responses of plates subjected to blast and impulsive loads. Navier’s approach was employed in order to obtain the equations for displacements and moments. The method validity was evaluated by making comparisons between the analytical and the numerical predictions of the plate time histories and the maximum displacement. A small discrepancy among the results proved the validity of the proposed analytical formulae. The effects of the plate aspect ratio, the thickness, and the charge weight on the plate deflection due to the blast loads were investigated by employing analytical and numerical approaches. The plate displacement changed linearly with respect to the charge weight, whereas it had a nonlinear variation for the plate thickness.
