A modified Johnson–Cook model for tensile behaviors of typical high-strength alloy steel
Materials Science and Engineering: A, 2010Abstract The uniaxial tensile tests were conducted with the initial strain rates range of (0.0001–0.01) s−1 and the temperature range of (1123–1373) K for typical high-strength alloy steel. Based on the experimental results, the modified Johnson–Cook model, which considers the coupled effects of strain, strain rate and deformation temperature, was ...

The formation of mild steel (MS) and copper (Cu) explosively formed projectiles (EFPs) was simulated in AUTODYN using both the Johnson-Cook (JC) and modified Johnson-Cook (JCM) constitutive models. The JC model was modified by increasing the hardening constant by 10%.

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 ...

Because of their superior ballistic and mechanical properties, lightweight materials like titanium alloy Ti-6Al-4V and aluminum alloy AA5083-H116 have been frequently used for aerospace and military applications. Tests of ballistic limit velocity are limited by expensive nature of the experimental setup, and indeed, that can be resolved by adopting ...

An empirical expression describing the electroplastic deformation behavior is suggested based on the Johnson-Cook (JC) model by adding several functions to consider both thermal and athermal electric current effects. Tensile deformation behaviors are carried out for an AZ31 magnesium alloy and an Al-Mg-Si alloy under pulsed electric current at various ...
