Given the importance of temperature in the dislocation density of crystalline materials, constitutive thermo-mechanical models provide a pathway for a more accurate description of temperature-sensitive processes. Commonly, however, the thermo-mechanical description of the material response is limited to phenomenological macroscopic models with limited interpretability. Here, thermal expansion is included in the single crystal constitutive response via an eigenstrain contribution to the deformation gradient, and a fully coupled implicit thermo-mechanical formulation is implemented into the variational framework of the crystal plasticity finite element method. Such a thermodynamically consistent model with temperature and micromechanical fields is used to investigate the response of different materials under thermal-stress boundary conditions.
