During Johnson-Cook plasticity modelling in ABAQUS what properties besides the J-C constants are needed to be given?

Only temperature dependence is to be considered but I can’t find the way to enter the working temperature or is it defined in the predefined field?

Hi,

When your model is temperature-dependent and has a high strain rate like impact, you should use the Johnson-Cook theory.

Depending on your simulation, you can define other variables as well. For example, in high-speed manufacturing processes where a large amount of inelastic strain exists, you need to define Inelastic Heat Fraction behavior, which indicates the energy dissipation rate as heat.

I recommend referring to the link below to see some examples and become more familiar with the Johnson-Cook theory.
