Simulation Analysis Of Stress In Bone And Implanted Hydroxyapatite Using Finite Element Method

Internal architecture has a direct impact on the mechanical and biologicalbehaviors of porous hydroxyapatite (HA) implant. Based on investigating lots ofrelative documents, porous hydroxyapatite (HA) implant is selected as researchobject in this paper. A geometry model of the hydroxyapatite implant and themiddle of femur was built up in the Pro/E software. A three dimension modelwas built up in this paper by using the three dimension finite element method inthe MARC software.The hydroxyapatite implant was analyzed in different internal architectures andvaries loads. The module displays the stress distributing state. The simulationresults show that the phenomenon of stress protection can be abstained whenhydroxyapatite implants were at lower porosity.This paper combined the finite element method and the computer simulatestechnology analyzing the stress influence of the hydroxyapatite implant and themiddle of femur in different internal architectures and varies loads. It providedthe theory and design basis on the hydroxyapatite implant.
