Abstract

The stage of formalization is necessary for constructing an adequate mathematical model of any phenomenon. By the example of a deformable polycrystalline material, it is shown that the formalization algorithm is based on a closed set of definitions, which represents the material under study as an open nonlinear dynamic structurally stable hierarchical (multilevel) dissipative self-organizing information system. Formalization principles, as applied to models of plastic deformation under static loading, are experimentally verified with polycrystalline fcc materials (MO copper and 08Kh18N10T austenitic steel).
