Title: Numerical evaluation of various significant activities in the design of artificial hip joint components.
Authors: Saxena, Sanjeev1 (AUTHOR) sanjeev.ampri@csir.res.in

Abstract: Accurate modeling of the complex mechanical behaviour of the hip joint is required to evaluate joint performance and understand experimental results. Numerical simulations of the hip joint available in the literature generally assume a concentrated load acting on the femoral head. While performing different activities with a hip implant, these simulations also do not account for changes in the areas of the femoral and acetabular cups that come into contact, or for changes in the peak load direction. The presented numerical work tries to address these issues. The numerical results indicate that sitting and slow walking are the critical activities for the design of the femoral and acetabular components, respectively. It is concluded that the von-Mises stress parameter governs the design of the femoral component, whereas the contact pressure parameter governs the design of the acetabular cup component. It is also found that the surface contact area of two components (femoral and acetabular cup) and the direction of peak load are the two parameters that govern the design of hip joint implant.
