Determination of Johnson–Cook parameters from machining simulations

Computational Materials Science, 2012
Abstract The plastic behaviour of material can be described using parametric material models such as the Johnson–Cook model. The parameters for such models are identified from experimentally determined flow curves by curve fitting techniques. In high speed machining processes, one encounters strains of more than 200% and strain rates of the order of ...

A comparative study on Johnson-Cook and modified Johnson-Cook constitutive material model to predict the dynamic behavior laser additive manufacturing FeCr alloy

Journal of Alloys and Compounds, 2017
Abstract An accurate prediction of flow behavior of metals considering the combined effects of strain, strain rate and temperature is essential for understanding flow response of metals, and a key requirement for numerical modeling and simulation of machining. Thus, the effects of high strain rate and elevated temperature on the deformation behaviors
