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.

Keywords: residual stresses distribution, cylindrical specimen, semicircular notch, finite element method.
