MODELING OPEN-CELLED ALUMINUM FOAMS STRUCTURE USING 3-D VORONOI DIAGRAM

Abstract

ABSTRACTThree dimension (3-D) Voronoi diagram is used to model open-celled Aluminum foamstructures. This model simulates the compression response of open-celled Aluminumfoam. Models of aluminium foam with different relative density and different cellregularities are used in simulations using ABAQUS. Finite element analysis (FEA)has been carried out to simulate the compression process on Aluminum Foam up to15% strain. Stress-strain curve relation is predicted for each model. The results showgood agreement with published experimental and mathematical modeling works. Thedeveloped model could be accepted as a virtual platform for modeling open-celledAluminum foam structure.
