Numerical simulation of the effect of blast shock wave on target plate

Numerical simulation of the shock wave propagation process of explosives with different charge amounts is carried out with the nonlinear dynamics software AUTODYN, and the influence law of the shock wave generated by the explosion of different explosive equivalents on the deflection change of the target plate at different distances is explored, and the fitting formula for the deflection change of the target plate with different charge amounts at different burst distances is given. The fitting results of this paper can provide reference for the failure of the equivalent target plate.
