Abstract:
For the local gradient approach in thermomechanics, the regularities of nearsurface nonhomogeneity in nonferromagnetic electroconductive solids, including the size effect of the ultimate stress limit are studied. It is noted that surface values of interaction energy and thermodynamic electric potential are determined by physical and geometrical properties of a body.
