Abstract In the framework of a research project on the performance criteria of cold formed structural steels [1] , a study of fatigue behaviour is being carried out by means of the determination of the Wohler curves (S–N) in 15 mm thick plates with different steel qualities and 15 mm diameter holes, made by punching and drilling. The different behaviour obtained has been associated with the different local damage done by the two processes near the hole surface, promoting different conditions… CONTINUE READING
