In this thesis, a novel 'layered' model for simulating the quasi-static and dynamic collapse of foam-filled ultralight aluminium structures using three-dimensional elasto-plastic finite element analysis is presented. Specifically, the quasi-static and dynamic axial collapse of foam-filled box columns is investigated. The column was modelled using shell elements, while the filler foam was modelled as a series of solid layers with a shear-stress failure criterion, which ties the layers together. This method enabled the simulation of the shear rupture of the foam, as observed in the extensive mechanical testing carried out in support of this study. The interface between the filler and the tube was modelled using an automatic contact algorithm, which incorporates the penalty method. The finite element analysis consisted of two investigations. In the first, aluminium columns of varying dimensions filled with aluminium foam of varying densities undergoing quasi-static axial crushing were examined. The effect of foam density, wall thickness and width of the column on energy absorption was evaluated and discussed. In the second, the same geometry was explored under dynamic impact loading.
