Finite Element Simulation of Pore Morphology and Stress Distribution of Porous Titanium

Abstract:

Porous Ti with an average pore size of 200-400 μm and porosity in the range of 25-50% has been manufactured using polymethyl methacrylate (PMMA) powders as spacer particles. The stress distribution of porous Ti was analyzed by Ansys software. The stress is prone to focusing on the surrounding of connected pore and weak cell. As the porosity and pore size increase, the concentration factor of stress increases due to the lager degree of pore connection and aggregation. Comparing with the ellipsoid pore model, the concentration factor of stress of the porous Ti with spherical pore is lower.
