Finite Element Modeling of Porous Microstructures With Random Holes of Different-Shapes and -Sizes to Predict Their Effective Elastic Behavior

Abstract: Porous materials are promising media for designing medical instruments, drug carriers, and bioimplants because of their excellent biocompatibility, ease of design, and large variation of elastic moduli. In this study, a computational strategy using the finite element method is developed to model the porous microstructures and to predict the relevant elastic moduli considering the actual characteristics of the micropores and their distributions. First, an element-based approach is presented to generate pores of… Show more

“…The reason could be attributed to a critical behavior. The overall mechanical properties are influenced by the pore shape and distribution, key features affecting the porous structure connectivity. Further thermochemical foaming, however, would lead to pore breakout and an evolution of destruction. Moreover, the samples’ shape and size were changed during the thermochemical foaming process.…”
