Abstract

ABSTRACT
Three dimension (3-D) Voronoi diagram is used to model open-celled Aluminum foam
structures. This model simulates the compression response of open-celled Aluminum
foam. Models of aluminium foam with different relative density and different cell
regularities are used in simulations using ABAQUS. Finite element analysis (FEA)
has been carried out to simulate the compression process on Aluminum Foam up to
15% strain. Stress-strain curve relation is predicted for each model. The results show
good agreement with published experimental and mathematical modeling works. The
developed model could be accepted as a virtual platform for modeling open-celled
Aluminum foam structure.
