Common types:

). These properties are essential because transient heat transfer depends on the rate of change of internal energy. : : Rapid cooling initially, slowing asymptotically

Most materials have temperature-dependent (k), (c_p), and (\rho). In Abaqus, define these as tabular data:

Use in material definition: Thermal → Latent heat → specify enthalpy per unit mass and temperature range. Required thermal properties:

: Animate over time steps.
