Effect of Pore Morphology on Deformation Behaviors in Porous Al by FEM Simulations

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.

The effect of particle shape on mechanical properties of perlite/metal syntactic foam

“…The findings presented in the previous section are in good agreement with experimental [14] and numerical studies [11]: foams with near spherical pores exhibit superior mechanical properties. According to Cho et al [11], the pore aspect ratio has a major effect on mechanical performance of the foams. Their finite element analysis showed that models with spherical pores have considerably higher strength when compared to ellipsoidal pores.…”

“…Moreover, the effect of cell morphology was often disregarded. Cho et al applied finite element method to investigate the effect of pore shape on mechanical properties of porous metals [11]. Comparing ellipsoidal and spherical pore shapes, they found that models with ellipsoidal pores have inferior mechanical properties compared to models containing spherical pores.…”

Structure Optimization of a High-Temperature Oxygen-Membrane Module Using Finite Element Analysis

“…5. Computer simulation, which is used to analyze the weak points in the membrane, predict the stresses in the OTM module system, and optimize or verify production [53,57,[59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76]. Although a few researchers have studied hollow and tubular modules, limited research has been devoted toward plate-type modules.…”
