| Abstract Scope |
Constitutive thermo-mechanical models allow for a more accurate description of temperature sensitive processes and often provide a pathway for a more rigorous thermodynamic description of crystal plasticity, given the importance of temperature in the dislocation density of crystalline materials. Commonly, however, the thermo-mechanical description of the materials response is limited to phenomenological macroscopic models with limited interpretability. In this work, 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 thermodynamically consistent model with temperature and micromechanical fields is used to investigate the response of different materials under thermal-stress boundary conditions. |
