近端股骨的结构模拟

摘要/Abstract

摘要： 利用Mullender M G,Huiskes R和Weinans H提出的骨自我组织控制过程,采用有限元与骨自优化理论相结合的方法来模拟近端股骨的结构,其结果是消除了早期模型中常见的方格盘现象,并且所预测的近端股骨的结构与实际结构非常吻合。

Abstract: Recently two types of discontinuities have been observed in the structural simulations of proximal femur.The first type called near field behavior appears in areas near distributed load application and is characterized by a checker board pattern of density.The second type of discontinuity called far field behavior appears remote from the load application and is characterized by strut or column like regions of elements.In fact,the far field discontinuity is an accurate representation of bone physiology and morphology.On the other hand,the near field discontinuity is a false representation of bone structure and violates the continuum assumption underlying the finite element method.The objective of this article is to devolop structural simulation of proximal femur as a self organizatinal control process by M.G.Mullender(1993),with the finite element method and bone self-optimization theory.The end configuration not only eliminates the checker-board density distribution typical of the early models,but also predicts a reasonably accurate density distribution.

Key words: structural simulation, bone self-organizational control process, bone self-optimization theory, finite element method, femur
