    Abstract: In this paper, fatigue life extension results from pre-existing surface defects in cast steel ASTM A148 90-60 of railway couplings, used in service in Portugal for coal transportation, are presented using two crack growth relationships (Paris equation and modified Paris equation). Fatigue lives were obtained and the results were discussed in terms ... Show More
