FIELD: machine building.
SUBSTANCE: sample is cut out in form of rod with rectangular cross-section. From sample thin layers of material are removed, starting from layer with minimum thickness 8-12 mcm, and increasing the thickness of next layers to maximum 35 mcm of last layer. Thickness of each removed thin layer and increment of sample deflection due to each removed thin layer are determined, then residual stresses in thin layers of materials are calculated as per equation.
EFFECT: simplified method, reduced labour intensity and increased accuracy of determination of residual stresses in surface layers of part.
