マグネシウムの材料特性を考慮した医療用ステントの最適デザインに関する研究

抄録

Magnesium alloys have biocompatibility and are suitable for weight reduction, so their application to medical devices is progressing. However, it is difficult to product design its optimum shape by magnesium, because magnesium is an HCP structural material and exhibits peculiar deformation behavior such as the SD effect. In this study, we performed a bending analysis for medical stent that introduced the SD effect for material model. Based on the results, topology optimization was performed and we considered how to design of magnesium stent which conditions where both compression and tension are present.
