Fatigue strength of shear loaded welded joints according to the notch stress concept

The NOTCH‐STRESS CONCEPT for the fatigue assessment of welded components in the version proposed by SEEGER [1] is presented in all aspects of material fatigue resistence formulation and application for local pure shear stress. Using the data from numerous tests with welded joints the concept is demonstrated up to the determination of local S– N‐curves and the characteristic fatigue reference values τ_a, A at N = 2·10⁶ load cycles from a statistical analysis of the test results.
