这篇论文是为Y教授的荣誉而写的。C.他是一位应用力学家，在生物力学方面做出了重大贡献。他的工作在肌肉骨骼生物力学领域产生了巨大的副产品效用。本文遵循T。Kawai（1978）对梁、板和壳结构以及土-砾石混合物地基进行了非线性分析，我们推导出了一种广义离散元分析（DEA）方法，用于确定人体关节接触压力、约束韧带张力和骨-植入物界面应力。回顾了DEA方法求解线性问题的基本公式。简要总结了正常关节接触问题中软骨非线性弹簧的推导过程。数值实现的DEA方法的线性和非线性弹簧。该方法能够产生与经典接触应力问题（赫兹解）和在选定模型上使用有限元建模（FEM）技术相当的结果。在人体膝关节和髋关节的选定应用程序进行了演示。此外，使用2D平面应变方法分析了非骨水泥固定中的股骨关节假体柄/骨界面应力。DEA方法的优点是易于建立模型，减少计算时间的不规则几何形状的关节。然而，对于关节组织应力分析，FEA技术仍然是首选方法。
This paper is written to honor Professor Y. C. Fung, the applied mechanician who has made seminal contributions in biomechanics. His work has generated great spin-off utility in the field of musculoskeletal biomechanics. Following the concept of the Rigid Body-Spring Model theory by T. Kawai (1978) for non-linear analysis of beam, plate, and shell structures and the soil-gravel mixture foundation, we have derived a generalized Discrete Element Analysis (DEA) method to determine human articular joint contact pressure, constraining ligament tension and bone-implant interface stresses. The basic formulation of DEA to solve linear problems is reviewed. The derivation of non-linear springs for the cartilage in normal diarthrodial joint contact problem was briefly summarized. Numerical implementation of the DEA method for both linear and non-linear springs is presented. This method was able to generate comparable results to the classic contact stress problem (the Hertzian solution) and the use of Finite Element Modeling (FEM) technique on selected models. Selected applications in human knee and hip joints are demonstrated. In addition, the femoral joint prosthesis stem/bone interface stresses in a non-cemented fixation were analyzed using a 2D plane-strain approach. The DEA method has the advantages of ease in creating the model and reducing computational time for joints of irregular geometry. However, for the analysis of joint tissue stresses, the FEA technique remains the method of choice.
