Abstract
One suggest the study of a polycrystalline set behaviour by the intermediate of a new structural model. The volume element $V_0$, being homogeneous at a macroscopic scale, is considered to be composed of an infinite number of kinematically connected subelements with different thermomechanical features. The internal constants, reflecting the heterogeneities of the tension and strain tensor's fields, are determined by thermodynamic principles. The thermomechanical features of the subelements are also determined by proportional and isothermal tests of the thin-walled tubes strained by axial force internal pressure. Have being obtained constitutive equations sistem during the process of monotonous stressing which is based on the new flow conception of subelements (Change criterion from a reversible state in an irreversible state is determined by value vector projection of elastic deformation of the subelement on the tangent for the irreversible deformation trajectory.Universitatea Tehnică
