The objective of this work is to evaluate the influence of incidental overloads on the fatigue behavior of steel plates welded by points and aimed for automobile application. An experimental test campaign on specimens had allowed the establishment of effort curves – life cycle of three types of steel welded by points and subjected to tensile-shear efforts under constant amplitude (reference curve), and with incidental overloads happening once (overloaded cycle) for 100 applied cycles. Specimens used in the test are made of two rectangle plates joined by a welded point and done by resistance welding. Two overloads ratio, 1,4 and 2,3 were tested and analyzed. The overall overloading cycle presents the ratio of 0,1 (undulated tensile effort). ...
