Determination of Material Constitutive Laws for Inconel 718 Superalloy Under Different Strain Rates and Working Temperatures
TL;DR: In this paper, a special procedure for the prediction of parameters of the Johnson-Cook constitutive material models is proposed based on the experimental data and specially developed MATLAB scripts which allow advanced modeling of complex 3D response surfaces.
FEM-Based Modelling of the Influence of Thermophysical Properties of Work and Cutting Tool Materials on the Process Performance
TL;DR: In this paper, the influence of constitutive model parameters on the results of FEM-based modelling of the turning process under simple orthogonal arrangement was considered and the sensitivity analysis concerned the material flow stress in the power constitutive law (PL) model.
