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.
