To explore the influence of material properties and strain rate on the compressive performance of open-cell aluminum foam under high strain rate, a series of simulations were conducted. A modeling approach based on 3D Voronoi technology was used to generate models with various parameters. Simulations were performed using ABAQUS/Explicit, and the simulation outcomes were compared with the corresponding SPHB experimental data to verify the accuracy of the modeling method. Models with varying porosities(55%,65%, and 75%), pore sizes(1.5, 1.0, and 0.5 mm), and strain rates were generated for simulation. The influence of material parameters and strain rate on the compressive performance was discussed and analyzed. The results demonstrate that within the range of parameters considered in the simulations, reducing porosity, enlarging pore size or increasing strain rate can enhance the plateau stress and energy absorption capacity of open-cell aluminum foam, thereby enhancing the compressive performance.
