Chelyabinsk scientific school of strength engineers: results and prospects

Abstract

The paper reviews new research areas created by D.A. Gokhfeld’s school and their application to the analysis of deformation and fracture of materials and structures under repeated (low-cycle) loads:

• incremental collapse at thermal cycling;
• mathematical theory of elastic and inelastic shakedown;
• low-cycle deformation and fracture of brittle (low-plastic) materials and structures
  (including artificial graphite);
• crack patterns in natural and man-made objects;
• repeated dilatational effects of environment (hydrogen, natural gas, etc.);
• stable and unstable deformation properties of steels, alloys and other materials, and their mathematical modeling;
• instabilities of inelastic low-cycle deformation processes;
• peculiarities of deformation and fracture of structures with a cyclically changing structure (including freezing and melting of the environment).

The paper outlines prospects for the research development, which is primarily related to the transition from ensuring reliability to ensuring the safety of structures, as well as expanding applications.
