Reading the possibilities to decode the microstructure characteristics from macroexperience

Abstract

The paper present the problem of practical application of relationships between the structure and proprieties. Here, it is emphasised that the symmetry elements of crystal lattice, the phases weight and the type of interatomic bond create measurable effects at macroscopic level. On this basis we succeed to formulated not only the direct problem, i.e. to deduce the constitutive equations at macroscopic level by means of constitutive equations at microscopic level, but the inverse problem, which, beside the practical importance, has a great methodological significance too. The knowledge possibilities in both directions allow us to adequately describe the material behavior as a function of external action development. The study is concentrated on the non-linear effects provoqued by the differences between the symmetry elements at macroscopic and microscopic level, prorogued by the differences between the symmetry elements at macroscopic and microscopic level, respectively, and also by the presence of several phases in the studied material, which are generated in the field of elastic strains.
