The Johnson-Cook plasticity model:
is a particular type of Mises plasticity model with analytical forms of the hardening law and rate dependence.
is suitable for high-strain-rate deformation of many materials, including most metals.
is typically used in adiabatic transient dynamic simulations.
can be used in conjunction with the Johnson-Cook dynamic failure model in Abaqus/Explicit.
can be used in conjunction with the tensile failure model to model tensile spall or a pressure cutoff in Abaqus/Explicit.
can be used in conjunction with the progressive damage and failure models to specify different damage initiation criteria and damage evolution laws that allow for the progressive degradation of the material stiffness and the removal of elements from the mesh.
must be used in conjunction with either the linear elastic material model or the equation of state(EOS) material model.
Uses a Mises yield surface with associated flow.
