| Abstract | Solution of Contact problems such as the three-body femur, meniscus and tibia analysis in the knee are an essential part of research in diarthrodial joint mechanics. There are numerous studies which focus on geometry [1], load transfer during articulation [2], and material properties of the components of the knee joint [3], for example. Results from experimental investigations of this problem are limited, however, as there are few variables that can be measured directly. To gain a greater understanding of contact in joints, we turn to the finite element method to construct numerical solutions for this complex problem. |
