“…To allow for the phenomenon of overelasticity resulting in an increase of the yield limit if the state of stress is spatially non-homogeneous, Konig (1974) where K is the yield parameter. The material is said to be ideally or perfectly plastic.…”

“…Based on the experimental data analysis [1][2][3][4][5] the yield strength of the material has been revealed to be determined in the course of tests for uniaxial tension does not allow for the strength problems accurate solution in the case of stresses nonuniform distribution. A series of gradient criteria of strength taking into account the stress distribution nonlinearityin the vicinity of the point under consideration for various materials exist there at the present time [6][7][8][9][10][11]. In the present paper, the authors use the yield criterion for elastoplastic isotropic material with a yield plateau.…”

“…В качестве меры неоднородности используется вектор-градиент скалярного поля напряжений. В ряде работ [2][3][4][5][6][7][8][9][10][11] такое влияние упругодеформированных областей материала учитывалось на уровне условий пластичности, когда началу пластического течения отвечают повышенные градиентные напряжения gr  . Однако такое предельное состояние не может появиться мгновенно, оно является итогом всего процесса деформирования.…”
