A thermodynamically consistent formulation of the Johnson–Cook model
Mechanics of Materials, 2020 Abstract The model of Johnson and Cook, which includes a viscoplastic flow rule and a damage criterion, is widely used to describe the mechanical behaviour of metallic materials subjected to severe loading conditions, such as those encountered during fabrication operations or impact.

Parameter Sensitivity Study of the Johnson-Cook Model in FEM Turning of Ti6Al4V Alloy. [PDF]
Materials (Basel)The aim of this study was to analyse in detail the effect of varying the parameters of the Johnson–Cook (JC) material model on the results of a numerical simulation of the orthogonal turning process of the Ti6Al4V titanium alloy. The first step involved an experimental study, including the recording of cutting force components and temperature, as well ...

Calorimetric consequences of thermal softening in Johnson–Cook’s model [PDF]
Mechanics of Materials, 2013 At high loading rates, the development of adiabatic shear bands in metals is conventionally attributed to the strong interactions induced by viscoplastic dissipation within the bands and thermal softening effects. The rheological equation proposed by Johnson and Cook takes both viscoplastic hardening and thermal softening into account.
