The incremental plasticity condition application for pure bending of a curved bar (Golovin problem)

The incremental plasticity condition application for pure bending of a curved bar (Golovin problem)

The limiting elastic state of a bar with large curvature under pure bending is considered on the basis of the elasticity theory exact solution. As a criterion for the limiting state, the gradient plasticity condition is used, which determines the yield onset in an inhomogeneous stress state. Analyti...
