An image processing technique was used to model the internal structure of aluminum foam in finite element analysis in order to predict the compressive behavior of the material.Finite element analysis and experimental tests were performed on aluminum foam with densities of sten jacket m 0.2, 0.25, and 0.3 g/cm3.It was found that although the compres
