METHOD FOR CALCULATING NOTCH STRESSES IN A WELD SEAM

摘要

Method, carried out by means of a computer, for calculating notch stresses (Ã K) on a component cross-section to be evaluated of a component (1) having at least one weld seam (2),wherein in the cross section (4) to be evaluated at least one local notch and / or root notch of the at least one weld seam (2) is modeled by a notch radius (3) selected according to the notch stress concept,wherein the evaluated cross-section (4) is acted upon by a defined load. According to the invention, it is provided that a sub-model which is dependent on at least one normalized unit load (E 1,..., E n; EX) is used, the Inertia-Relief method being used to generate the sub-model in order to produce unitary Partial notch stresses (Ã TE (EX)) due to the unit loads (EX) and that the notch stresses (Ã K) due to the actual prevailing load condition of the section (4) to be evaluated by linear combination and superposition of the unit part notch stresses (Ã TE (E 1), ..., Ã TE (E n), O TE (EX)) are calculated to allow exact calculation of notch stresses (Ã K) without having to make assumptions about the boundary conditions.
