Abstract

In the present work, effect of porosity and pore shape on compressive deformation behaviors of porous Al is analyzed using three-dimensional finite element method. Representative volume elements of porous microstructures, having four different pore morphologies, are reconstructed using random sequential adsorption algorithm. The numerical results suggest that consideration of pore morphology can give qualitative information on deformation behaviors of porous metals, and thus may be helpful to design and optimize of the materials.
