Thermoelastic constitutive law

Understand the Thermoelastic constitutive law relationship used by Thermal Expansion.

Where to find it

Thermal Expansion → equations

How to use it

Compare the terms, signs and units with your intended physical assumptions before choosing model inputs.

Result

Equation: \boldsymbol{\sigma}=\mathsf C:\left[\boldsymbol{\varepsilon}-\boldsymbol{\alpha}(T-T_{\mathrm{ref}})\right].

Troubleshooting

The equation describes the model assumptions; it is not a separate editable boundary condition. Check the parent physics page for setup and limitations.
