The stress distribution heterogeneity influence on the limiting state of a bent curvelinear beam

The limiting elastic state of a beam with large curvature under pure and transverse bending is considered. The gradient plasticity condition which determines the yield onset in an inhomogeneous stress state is applied as a criterion of the ultimate state. The analytical expressions for calculating t...

Description
Summary:The limiting elastic state of a beam with large curvature under pure and transverse bending is considered. The gradient plasticity condition which determines the yield onset in an inhomogeneous stress state is applied as a criterion of the ultimate state. The analytical expressions for calculating the corresponding stresses and loads are obtained.
