DETERMINATION OF THE NON-AXISYMMETRIC STRESS STATE IN THE PLASTICITY ZONE BY THE HOLE-DRILLING METHOD WITH OUT-OF-PLANE ESPI
: The stress state estimates accounting for plasticity are obtained at residual stress evaluation performed by hole-drilling method and out-of-plane ESPI. The plasticity zone in the sample is present prior to the probe hole drilling. The sample is a steel composite disc, assembled by fitting rings on the plug. The initial stress distribution in the composite elastic-ideal plastic disk accounting for the formation of a plastic zone in the covering ring is obtained by the solution of Gadolin in elastoplastic formulation. A simple analytical algorithm to adjust the non-axisymmetric stresses in comparison with the calculation according to the elastic model is developed. The case of probe hole drilling in the area of plastic deformations is considered.
