Abstract

In this paper, a numerical study is conducted to model the mechanical behaviour of aluminium foam under compressive loading using the representative volume element (RVE) method. Tetrakaidecahedrons are selected as cells to form the RVE model for modelling the mechanical properties of the aluminium foam. The study is conducted Via the commercial finite element code Ansys-LS Dyna. The three-dimensional solid element 164 is used to mesh the RVE model. This micro-structured RVE model is used to model the mechanical behaviour of aluminium foam of density of 230 kg/m3 under quasi-static compressive loading. A convergence test is firstly conducted to decide the mesh density. The stress-strain relationship obtained from the numerical modelling is compared to that from experimental study and the agreements of the results demonstrate the efficiency of the RVE model. The deformation process of the RVE under the compressive loading obtained from the numerical simulation is also presented.
