... of steels and different geometries that have been welded, cold bent, repair welded, or overloaded, was used as a ‘Master curve’ of the residual stresses. In all cases compared, it has been shown that the transverse measured residual stresses were tensile at the surface The stress intensity factor (SIF...

... cycle fatigue loading that nucleated a crack. The increase in fatigue limit was attributed to an overload effect from the LCF loading and was quantified through the use of a simple overload model. On the contrary, evidence from R = −1 testing suggests that negative overloads, referred to as underloads...

...N Ranganathan; A Tougui; F Lacroix; J Petit This paper presents the behavior of selected aluminum alloys when subjected to a single overload, with an aim to highlight the effects of plasticity and environment. The delaying effect of a single overload is given in terms of number of delay cycles...

...P Darcis; N Recho This paper deals with the reliability analysis of the influence of an overload on the fatigue design of welded joints. The modeling of the fatigue life is presented as the sum of four parts: the first one concerns the fatigue life initiation, the second one involves the fatigue...
