Abstract

Based on the stress wave theory, the optimal configuration of gradient aluminum foam is given. On this basis, a simulation model using three-layer gradient aluminum foam gasket is established, and two typical configurations and four impact angle conditions are numerically simulated. Simulation results show that the density of aluminum foam gradually decreases along the direction of impact load propagation is a better configuration, which is consistent with the previous theoretical analysis results, and the protective performance can be simply and effectively improved by changing the configuration of aluminum foam.
