On the application of two-dimensional finite element model for biomedical analysis.

In this paper, a technique for applying two-dimensional finite element model to biomedical analysis is studied. The analytical models for total hip replacement (THR) and total knee replacement (TKR) are proposed as the in-plane strain and stress models, respectively. In these models, many convenient approximations are applied for the load conditions, structural shapes and material properties. The stress distributions and deformations calculated for the models of THR and TKR are compared with the results obtained by the corresponding experimental models. From these results, the availability of the two-dimensional finite element model for biomedical analysis is discussed.
