Abstract
Results of materials testing for lead-free brass show that the effect of thermal softening decreases significantly when the strain rate is high. This behavior is referred to as thermal softening damping. In this article, a flow stress model with thermal softening damping based on the Johnson-Cook flow stress model was developed. Finite element simulations with the proposed model are compared to cutting experiments to estimate the effect of damping in metal cutting.
