Johnson–Cook strength modelJohnson〤ook (JC) high temperature strength material models have been widely used in Finite Element Analysis (FEA) to solve variety of hot rolling problems. In this paper, the temperature and strain rate related parameters of JC model were experimentally calibrated for ...
New Split Johnson–Cook strength model In this section, a new hardening model is introduced, which is referred to as Split Johnson–Cook (SJC) strength model. Since the new model derives from the classical JC model, it keeps an empirical nature. This aspect is central in order to properly ...

Johnson–Cook model Metals Temperature dependence Constitutive parameters Introduction It is well known that metal mechanical performance, such as yield stress, ductility, and strength, are related to loading conditions [1], [2]. Rate and temperature dependences of mechanical properties are believed to...
