Abstract
This paper proposes a mathematical model of heat transfer in the cemented hip replacement using the metal-metal implant with no cup. Computational domain consists of three subregions including a femur region, an implant region and a femoral canal region. The femoral region is divided into two parts which are the top and the bottom parts occupied by the cement and the ambient air. The governing equation is a unsteady heat equation. Heat transfer by conduction is considered in this study. Finite element formula for the solution of heat transfer problem is derived. Effect of the initial temperature of the cement and the implant material on heat transfer process are investigated. Numerical results show that the initial temperature has significant effect whereas the implant materials has less effect.
