Determination of Flow Stress Based on Cutting Simulation and Optimization
A new simple methodology to determine the flow stress of material is presented and Johnson–Cook (JC) constitutive model of titanium alloy Ti6Al4V is obtained via this approach. The JC model is verified by comparison between simulations and experiments. The results show that the model is suitable for cutting simulation. This simple method can be used to determine conveniently JC model not only in the scientific research but also in the workshop production.
