From the results of the analysis on the internal fixation of the tibia for two contact models, it was found that the use of the frictional contact model in the simulation of the Finite Element Analysis (FEA) is suitable for the geometry model of the tibia with fractured. The bonded contact model is suitable for the geometric model in which the tibia has completely healed, but the internal fixation has not been removed.

C ONCLUSIONS

I

n this study, the contact model has an influence on the results of the finite element analysis as the hypothesis developed at the beginning of the study. Two different contact models, namely the frictional contact model and the bonded contact model, produce a different magnitude and distribution of von Mises stress on the plate used. The frictional contact model seems to be more suitable for initial plate placement conditions where the two fractured bones have not yet fused, while the bonded contact model is more suitable for fracture conditions where the bones have started to fuse. Furthermore, the influence of the screw mounting angle on the analysis results are not yet known so further studies still need to be carried out.
