Finite element simulation of the plastic collapse of closed-cell aluminum foams with X-ray computed tomography

The detailed deformation and plastic collapse mechanisms of closed-cell Al foams under uniaxial compressive loading, which govern the energy absorption capacity of the foam material, are analyzed with the method of finite elements and experimental measurements. A three-dimensional (3D) finite element (FE) model for a real closed-cell Al foam specimen fabricated via the direct foaming route is constructed by employing the microfocus X-ray CT...
