Strength of electrically conductive non-ferromagnetic layer. Size effect. (Ukrainian, English) Zbl 1463.74049

The authors discuss the results of the investigation, by means of the local gradient approach in thermomechanics, of the equilibrium state of an electroconductive non-ferromagnetic layer with allowance for the geometric heterogeneity of its surface. It is shown that the surface stresses and strength are characterized by a multiscale size effect; the characteristic sizes of the near-surface heterogeneity are related with the structural heterogeneity of the material, the geometric heterogeneity of the body real surface, and the Coulomb interaction forces.
