Finite element design for Fatigue assessment of welded components.
In: 2nd Int. Conf. of Engineering against Fracture (ICEAF II), Mykonos, [Conference or Workshop Item]

Abstract

Modern welded structures often contain weld start and end points which are the failure critical location. In particular, for special investigations into thin sheet structures, no approach for the determination of the fatigue life has been established thus far. In this research, the primary aim was to obtain the real geometry of weld ends with high precision using a three dimensional scanner to find a general approach using the notch stress concept. Going one step further, analyses have been performed regarding to unify the notch stress concept so no differentiation between thin and thick sheet structures is necessary. To validate this approach, the thin sheet results are compared to a thick sheet component of a motor truck.
