摘要

本文通过有限元分析，探讨了钛合金、胶原增强聚合物基复合材料等现有生物材料用于踝关节植入的可行性。踝关节是人体承受最大压应力和承受最大变形的重要关节。它必须评估诸如应力集中、变形区和材料行为等特性。在ANSYS Workbench中进行了正常行走和冲刺等不同加载条件下的分析。分析表明，Ti-6Al-4V和30%胶原增强PMC均表现出最小的应力，但由于Ti-6Al-4V的密度大于30%胶原增强PMC。尽管在Ti-6Al-4V中产生的应力在屈服应力范围内，但密度仍然不够接近骨的密度。胶原蛋白增强的PMC密度接近骨骼30%，推荐作为种植材料，以获得更好的使用寿命和性能。

FEA Analysis of TI-6AL-4V and 30% Collagen Reinforced PMC Used as Biomaterials for Ankle Implants

This paper deals with the feasibility study of using existing biomaterials like titanium alloy and the collagen-reinforced polymer matrix composite for ankle implant application through FEA analysis. The ankle joint is the important joint in the human body that experience maximum compressive stresses and undergoes maximum deformation. It must evaluate properties like stress concentration, deformation zone, and material behavior. The analysis was carried out in ANSYS Workbench with different loading conditions, for instance, normal walking and sprinting. The analysis showed that both the Ti-6Al-4V and the 30% collagen-reinforced PMC exhibited minimum stresses, but since the density of Ti-6Al-4V is more than 30% collagen-reinforced PMC. Even though the stress developed in Ti-6Al-4V is within the yield stress, the density is still not close enough to the density of bone. Collagen-reinforced PMC with a 30% density close to the bone is recommended as an implant material for better life and performance.

期刊介绍： Biointerface Research in Applied Chemistry is an international and interdisciplinary research journal that focuses on all aspects of nanoscience, bioscience and applied chemistry. Submissions are solicited in all topical areas, ranging from basic aspects of the science materials to practical applications of such materials. With 6 issues per year, the first one published on the 15th of February of 2011, Biointerface Research in Applied Chemistry is an open-access journal, making all research results freely available online. The aim is to publish original papers, short communications as well as review papers highlighting interdisciplinary research, the potential applications of the molecules and materials in the bio-field. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible.
