Abstract

Abstract: The dynamic response of graded corrugated sandwich plates under air blast loading is investigated using Autodyn software. The effect of core arrangement on the response modes and blast-resistant performances of graded corrugated plates is analyzed. The graded corrugated sandwich plate with a certain core configuration is selected, which is filled with polyvinyl chloride foam. Furthermore, the influence of filling strategy on blast-resistant performances of sandwich structures is studied. The energy absorption property of sandwich structures is discussed. The results reveal that the sandwich plate, of which core web thickness gradually decreases from front face to back face, has the optimal blast-resistant performance. The deflection of bottom face sheet of sandwich plate is minimal, in which the first core layer was filled with foam. As polyvinyl chloride foam is filled into one of the layers of the sandwich plate from front face to back face, the energy absorption proportion of polyvinyl chloride foam continuously declines. The deflection of back face, and the energy absorption of polyvinyl chloride foam and bottom face sheet increase with the increase in the number of filling layers. Key
