TY - CONF A1 - Madia, Mauro T1 - Fatigue strength and fracture mechanics N2 - This invited plenary lecture is aimed at giving a General overview about the assessment of the fatigue strength of metallic components under constant Amplitude loading based on fracture mechanics. A particular Focus is put on the Evaluation of the fatigue crack driving force and material resistance to fatigue crack Propagation in the Regime of physically/mechanically short cracks. The potential of the methodolody is demonstrated on case studies dealing with the fatigue life prediction of welded joints.

The approach includes (a) a concept for short crack propagation for which the common K concept is not applicable and the crack closure effects are still being gradually build-up, (b) a method for determining fatigue life relevant initial crack sizes as they are needed in any fracture mechanics analysis and (c) multiple cracking and crack coalescence at load levels higher than the endurance limit. The analyses are stochastically performed. Both, the endurance limit as defined for 107 loading cycles and the finite life branch of the S-N curve are determined.
