A material's specific heat:

Defining specific heat

The specific heat of a material is defined as

where is the internal energy due to thermal effects only. The specific heat per unit mass is given as a function of temperature and field variables. When possible, large changes in internal energy during a phase change should be modeled using Latent heat, Section 20.2.4, not specific heat.

Specific heat effects can be defined for all heat transfer, coupled temperature-displacement, and coupled thermal-electrical elements in ABAQUS. Specific heat can also be defined for stress/displacement elements for use in adiabatic stress analysis.
