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 ...

Johnson-Cook Constitutive Equation for Titanium Alloy TC11
Key Engineering Materials, 2013Studying the dynamic properties of a material are an important method to understand the dynamic processes and deformation mechanism of material at different working conditions, particularly at high strain rate. The constitutive equation of a material has the highest significance to represent the mechanical properties, and is the principal research ...

Determination of Johnson–Cook Parameters for Cast Aluminum Alloys
Journal of Engineering Materials and Technology, 2014A series of experiments were conducted to determine the Johnson–Cook parameters for three different cast aluminum alloys, namely, A356, A357, and F357. Room temperature compression experiments were performed under varying rates of loading ranging from 10−3 s−1 to 5000 s−1.

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.

How To Identify Johnson-Cook Parameters From Machining Simulations
AIP Conference Proceedings, 2011The Johnson‐Cook material model is a robust material model which has demonstrated its usefulness in describing material behaviour over large ranges of strains, strain rates and temperatures. During machining the material in the shear zone undergoes strains of more than 200%, strain‐rates of the order of 106 per second or more and a temperature rise of ...

Materials & Design (1980-2015), 2013
Abstract The isothermal hot compression tests were conducted on a Gleeble-1500D thermal simulation machine, in a wide range of temperatures (1173–1373 K) and strain rates (1.5 × 10−3–1.5 × 10−2 s−1). Based on the experimental true strain-true stress data, the Johnson–Cook, modified Johnson–Cook and Arrhenius-type constitutive models were established ...

Determination of the Johnson–Cook Material Parameters Using the SCS Specimen
Experimental Mechanics, 2008This note addresses the determination of the Johnson-Cook material parameters using the shear compression specimen (SCS). This includes the identification of the thermal softening effect in quasi static and dynamic loading as well as and the strain rate hardening effect in dynamic loading.
