Analysis of stress state in semicircular profile notches after preliminary surface plastic deformation of solid cylindrical specimens

Abstract

The distribution of residual stresses of surface hardened solid cylindrical specimens and specimens with a semicircular notch using the finite element method is studied. As the initial information the experimentally determined one and / or two components of residual stresses in a hardened layer are used. It is noted that residual stresses redistribution on the stress concentrator is significantly affected by the ratio of a notch radius to a zero depth of axial component of residual stresses.
