Investigation of Residual Stresses in the Surface Layer of Parts of Intricate Shape,

Abstract

An investigation was made of residual stresses in the surface layer of parts of intricate shape; for example, blades of gas turbine engines. Proposed are the procedures and calculation for the axial residual stresses in the radius of the coupling of the foil and flange of the blades and tangential residual stresses in the edge of the blade foil. These procedures can be applied not only for the blades, but also for other parts which have similar elements, for example, the longitudinal paddles, the radius couplings of two surfaces, and so on.
