Constitutive Modeling of Inelastic Single Crystals for Localization Phenomena
The main objective of the present paper is the constitutive modelling of inelastic single crystals. A constitutive model is developed within the thermodynamic framework of the rate type covariance constitutive structure and takes account of the effects as follows: (i) thermomechanical coupling; (ii) influence of covariant terms, lattice deformations and rotations and plastic spin; (iii) dislocation substructure; (iv) rate sensitivity (viscosity).
