Abstract
This work evaluates the mechanical behaviour of elastic-plastic porous materials with cylindrical voids using a direct FE2 multi-scale framework. The study investigates the influence of the void volume fraction on the overall structural behaviour considering a simple tensile test of a plate. Despite its simplicity, the numerical study allows comparing the direct FE2 method with direct numerical simulations, in which the material heterogeneities are modelled considering a single scale. The comparison allows assessing specific numerical aspects related to the direct FE2 framework, such as its accuracy and the corresponding computational cost. This is a first step of our group toward multi-scale analysis employing the direct FE2 to model the mechanical behaviour of heterogeneous materials considering more complex morphology and loading conditions.
