The Compression Behavior Simulation of Aluminum Foams
The compression behavior of open-cellular Aluminum foams was simulated using DEFORM-3D software. The structures of regular tetrahedron, octahedron and tetrakaidecahedron (Kelvin) model were developed separately. Simulation results show that the models have similar compression behavior. Then load-time curves and strain-stress curves have similar characteristics, the linear elasticity at low stresses followed by a long collapse plateau, truncated by a region of densification in which the stress rises steeply. Compared with experiment, the platform stress and the Young’ model of the Kelvin mold have good consistency within the error range.
