T1 - Assessment of welded joints by fracture mechanics IBESS - the development of a procedure T2 - SoSDiD - 4th Symposium on structural durability in Darmstadt (Proceedings) N2 - The idea to determine the fatigue strength of weldments by means fracture mechanics was originally based on the empirical observation that the major portion of the fatigue life in weldments is frequently spent in crack propagation. The present paper gives a brief overview on the basic principles of fracture mechanics-based determination of fatigue strength and on special features which have to be considered for weldments. Based on this information, the ongoing research project IBESS is introduced and briefly reviewed.
