Abstract

Abstract

A bi-directional gradient bionic circular sandwich plate was designed by introducing out-of-plane gradient into in-plane gradient core on the basis of Royal Water-Lily. Based on this, the responses of various bi-directional gradient circular sandwich plates under different blast loadings were simulated by using the finite element software of ABAQUS. The deflections of front and back panels, compression, deformation mode and energy absorption of different cores were analyzed emphatically, and a core arrangement mode with better blast resistant performance was obtained. The results show that: compared with a single out-of-plane gradient sandwich structure, the deflection of the back panel of bi-directional gradient sandwich structures can be effectively reduced, and the energy absorption capacity of the core can be improved through the reasonable bi-directional gradient arrangement.
