Computational Modelling of Nanoporous Materials

Recently proposed constitutive models that describe the mechanical behavior of open-porous cellular materials take into account random pore sizes but not randomness in shapes [1]. In present contribution, a computational model to reconstruct highly irregular structure porous is developed using sphere packing and Laguerre-Voronoi tessellation [2]. The structure-property relationship then investigated by means finite element methods. Under compression, demonstrate linear-elastic behaviour followed an irreversible deformation resulting plateau region densification [3]. this such responses under cyclic loading are elasto-plastic material models. Furthermore, effects tensile on also discussed.
