Modified Johnson-Cook constitutive model of metallic materials under a wide range of temperatures and strain rates

This study concentrated on presenting the classical Johnson-Cook model by introducing a new temperature term, under the framework of an equivalence between heat energy and distortional strain energy. Importantly, the inner relationship among temperature, elastic modulus, the specific heat capacity a...
