Study on deformation of perforated plates under blast loading

Deformation of perforated plates under impulsive loading of blast wave was simulated by AUTODYN software and the deflection relationship of plates with different hole numbers and diameters was obtained. Experiments were designed and the consistency between model computation and experiment results was validated. A general perforated plate deflection formula was proposed based on deflection formula of non-hole thin plate and the computation results, which can provide reference for damage estimation of perforated plate and damage study on effects of fragment and blast wave.
