Determination of Johnson–Cook Plasticity Model Parameters for Inconel718
Journal of Materials Engineering and Performance, 2017In order to simulate foreign object damage (FOD) phenomenon in aircraft high-pressure compressor blades made of a nickel-based super-alloy, Johnson–Cook (J–C) plasticity model was used. For prediction of material’s plastic behavior at temperature of 400 °C (working temperature of the blades) in the range of strain rates associated with the FOD ...

Modified Johnson-Cook model for vehicle body crashworthiness simulation
International Journal of Vehicle Design, 1999Dynamic response prediction of vehicle bodies is important for vehicle crashworthiness evaluation. The dynamic behaviour of vehicle body materials is dependent on material strain rates. One of the typical high strain rate tensile tests is the split Hopkinson bar test.

Validation of the Tabulated Johnson-Cook Model for a Dynamic Compression Simulation
Applied Mechanics and Materials, 2015MAT224 is a tabulated version of the Johnson-Cook model in LS-DYNA. Compared with the original Johnson-Cook material, MAT224 was developed to simulate the dynamic response of a material by just defining the effective stress as a function of effective plastic strain at different strain rates and temperatures, thus avoiding the tedious parameter fitting ...

The Prediction Model of Cutting Forces Based on Johnson-Cook’s Flow Stress Model
Key Engineering Materials, 2008Thin-walled parts with complex configurations are extensively used in aerospace and precise instrument industry. However, because of low stiffness, cutting forces, clamping forces and residual stresses in cutting have been the main factors influenced on machining accuracy of thin-walled parts.
