Parameter definition
Variable
Description
tid
Unique thermal property identification number
$\alpha_T$
Heat expansion coefficient or ID of a CURVE defining $\alpha_T(T)$
$C_p$
Heat capacity or ID of a CURVE defining $C_p(T)$
$\lambda$
Heat conductivity or ID of a CURVE defining $\lambda(T)$
$k$
Plastic work heat conversion factor
$T_{ref}$
Reference temperature for thermal expansion
$\varepsilon$
Thermal emissivity
Description
Defines thermal properties that are linked to a material through tid in the material command.
The command collects thermal expansion ($\alpha_T$), heat capacity ($C_p$), conductivity ($\lambda$), plastic work heat conversion ($k$), reference temperature ($T_{ref}$) and emissivity ($\varepsilon$). Constants or CURVE-based temperature dependence can be used where supported by the material model.
In the material kernels, $T_{ref}$ is used together with $\alpha_T$ to evaluate thermal strain terms and pressure/volumetric response. Keep tid=0 in the material command when no thermal coupling is intended.
