  • A two-dimensional finite element model was created from a tomographic image of the aluminum foams, which represents the cell shape and geometric distribution of real foams.To determine the mechanical properties of cell wall material, the uniaxial stress versus strain curve, predicted numerically for aluminum foam, was fitted to that measured experimentally.We mainly discuss the shock wave propagation, the inertial effect and the strength of the stress on the stationary end of metallic cellular materials under high speed compression.As for aluminum foams with relative density 0.3, the elastic wave speed is calculated to be 5 km/s, whilst the plastic wave speed increases from 83 to 294 m/s, with the compression velocity increasing from 50 to 200 m/s.Within the compression velocity range of 50-100 m/s, the deformation modes change from random mode to progressive mode.However, no distinct critical velocity are observed.The dynamic locking strain increases with the increasing compression velocity.Second compression process occurs in metallic cellular materials when the plastic wave reflects on the stationary end.Accordingly, the second stress plateau appears on the stationary end, which increases with the increasing compression velocity due to inertia effect.
