AUTHOR Len Schwer CORRESPONDENCE - dynalook

A brief review of the standard Johnson-Cook model is presented. Three optional strain-rate forms are introduced and calibrated to laboratory data for A36 steel. Finally, all four calibrated strain-rate forms are exercised in single element uniaxial stress test simulations, and the results are compared with the A36 steel effective stress versus

Johnson - Cook Strength Models for Mild and DP 590 Steels

Abstract Automotive steels, Mild and Dual Phase590 (DP590) are characterized in tension at room temperature, using the quasi-static and split Hopkinson bar techniques at various strain rates ranging from ˜10-3 /s to ˜1800/s. Tension stress-strain data for both the steels are analyzed to determine the Johnson-Cook Strength model constants, J-C strength model constants for mild steel are A=217 ...
