Conference paper


The object of our investigation in the general case is a deformable curvilinear three-dimensional solid-state construction made of multiphase composite material of the “polycrystalline metal- polycrystalline metal” type, which phases are real polycrystalline aggregates and each grain is a reservoir of moving carriers of plastic deformation and microfracture — arrays of crystal lattice defects. In order to obtain a simplified workable image of studied object we introduce the hierarchical four-level model preserving main behavior features of construction considered. The principal structural levels of introduced model are:

1. L (0) , the level of the whole construction, 2. L (1) , the level of composite material structure. The characteristic object is the composite structure periodicity cell for regular composites or the representative volume (RV) for irregular ones, 3. L (2) , the level of the polycrystalline aggregates of composite phases. The characteristic object here is the poly crystal volume V (2) which is the representative sample out of the whole aggregate in the form of some anisotropic grain ensemble. 4. L (3) , the level of the single crystal discrete structure containing arrays of defects moving in the veritable crystallographic slip systems with specific misorientations.
