Micro-scale analysis of HA-PLLA bio-composites: Effect of the interpenetration of voids on mechanical properties

Reinforcement of hydroxyapatite (HA) particles into poly- l -lactic acid (PLLA) enhances the mechanical properties of PLLA and further makes it favorable to use in biomedical applications. A micro-scale computational model for predicting the effective elastic properties of HA-PLLA composites through 3D representative volume element was studied in the presented work. The influence of volume fraction of HA particles, the orientation of HA and...
