- 01H4KESZKZSCEQAXK5J0N7PESJ abstract "Ageing infrastructure is a major concern for industries across Europe. In this paper an overhead crane girder that is part of an ageing fleet of nearly identical structures with known fatigue cracking problems is studied. A global finite element model is developed, validated and used to drive submodels of different scales. Using load spectra based on real operational data, hot spot stress and fracture mechanics based fatigue lifetime calculations are performed using in-house developed numerical frameworks. Supported by a thorough literature review, the results of both methods are critically analyzed and compared. The estimated lifetime obtained using a fracture mechanics approach and an initial crack of only 0.1mm deep, differs two orders of magnitude compared to the endurance based hot spot stress approach. The study also revealed that a fracture mechanics based assessment is overly sensitive to the initial crack dimensions and material properties. Finally it is shown that the often used assumption of a constant aspect ratio can lead to overly conservative results.".
