Abstract

The dynamic response characteristic and protective performance of corrugated core sandwich panels subjected to underwater shock loading were investigated in the present study. Combined with the non-explosive underwater explosion shock loading experiments, the decouple method of fluid-structure interaction phase from plate response was validated by explicit dynamics simulation results.Based on the validated method, the dynamic response of corrugated core sandwich panels was studied. Then the relationship between non-dimensional applied impulse and plastic deflection of air back plate was observed in order to compare the protective performance between sandwich plates and monolithic plates. The results showed that the protective performance of corrugated core sandwich panels was effectively improved by 82.45% than monolithic plates in equivalent areal mass. Among the sandwich plates, the corrugated core panels behaved the better protective performance than lattice core panels.
