Temperature Calculations in Orthogonal Cutting of Cortical Bone Using Finite Element Analysis

摘要

The major concern in the current bone cutting research is thermal necrosis of the bone tissue, which occurs when the bone temperature rises above a threshold value. In this study a thermo-mechanically coupled finite element model of the bovine cortical bone is presented. The effect of a cutting speed on the temperature rise in the bone material is analysed. Temperature values in a bone are calculated and compared for cutting conditions with and without cooling (irrigation).
