| + | 0 & 0 & K_3 | ||
| + | \end{array} | ||
| + | \right] \nabla T, | ||
| + | $$ | ||
| + | where $\boldsymbol{K}$ is the orthotropic conduction matrix (in material axes) and $\nabla T$ is the temperature gradient. | ||
| + | |||
| + | Linear thermoelasticity in the orthotropic frame writes | ||
| + | $$ | ||
| + | \boldsymbol{\sigma} = \boldsymbol{\sigma}_0 + \mathbb{H} : (\boldsymbol{\varepsilon} - \boldsymbol{\varepsilon}^{th}) = \boldsymbol{\sigma}_0 + \mathbb{H} : (\boldsymbol{\varepsilon} - \boldsymbol{\alpha} \Delta T), | ||
| + | $$ | ||
| + | with stress tensor $\boldsymbol{\sigma}$, | ||
| + | |||
| + | Thermoelastic dissipation term $\dot{W}^{te}$ is given by the general (anisotropic) relation | ||
| + | $$ | ||
| + | \dot{W}^{te} = -\eta_{te} \left(\sum_{i=1}^3 \sum_{j=1}^3 \mathbb{H}_{ijkl} \alpha_{kl} \right)T \frac{\dot{J}}{J}, | ||
