Abstract

An efficacious method of evaluating the mechanical properties of a metal with the application of a composition of the topological and fractal approaches for the cellular, lamellar, granular, and needle-grade classes of a structure is proposed. It is based on four new criteria for the evaluation of new structures and allows one to reduce the error in the prediction of strength characteristics of a metal by 1.24—2.16 times depending on its class.

Keywordsclass of a structure, forecast of properties, fractal theory, metal, topology
