Abstract

In this study, a three-dimensional trabecular structure is constructed with the help of micro-computed tomography scan data of a rat distal femur, and the finite element analysis (FEA) is carried out to analyze the stress distribution. Compressive loads 1000 N, 2000 N, and 4000 N were applied in longitudinal and transverse directions. The FEA showed that the percentage increase of stress in the transverse direction is 22% compared to that in the longitudinal direction. An analytical analysis was conducted on a small section to validate the results and the estimated error is 7.16% between the analytical and finite element simulation results.

轻量化应用中小梁结构应力传播的有限元分析

摘要

本研究借助大鼠股骨远端的微型计算机断层扫描数据构建三维小梁结构，并进行有限元分析（FEA）分析应力分布。在纵向和横向上施加 1000 N、2000 N 和 4000 N 的压缩载荷。有限元分析表明，与纵向相比，横向应力增加的百分比为 22%。对一小部分进行分析分析以验证结果，分析和有限元模拟结果之间的估计误差为7.16％。
