+ | Linear thermoelastic orthotropic material with orthotropic thermal conduction law. | ||

+ | Thermal conduction writes in the orthotropic frame | ||

+ | 0 & 0 & K_3 | ||
+ | \end{array} | ||
+ | \right] \nabla T, | ||
+ | $$ | ||
+ | where K is the orthotropic conduction matrix (in material axes) and ∇T is the temperature gradient. | ||
+ | |||
+ | Linear thermoelasticity in the orthotropic frame writes | ||
+ | $$ | ||
+ | \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 σ, | ||

+ | Thermoelastic dissipation term ˙Wte is given by the general (anisotropic) relation | ||
