Abstract：Based on the theoretical calculation model of honeycomb structure static plastic collapse stress and Cowper-Symonds model, a metallic honeycomb structure collapse theory model under impact load on consideration of the strain hardening effect and double wall thickness of adhesive layer is established. The dynamics of aluminum alloy honeycomb structure out-of-plan deformation under impact load is simulated using LS-DYNA software. The results show that the plastic collapse theory model can more accurately predict the plastic collapse stress of honeycomb structure under out-of-plane impact loading by comparing with simulation and experimental data.
