“…In addition, the aerospace sectors are the only sectors that require a full-scale test of the complete structure, whilst due to size and economic considerations in the other sectors, only full-scale testing of components (e.g. welded joints in the offshore sector) is performed [20].…”

Abstract. This paper presents a review of the conservatism approaches applied by different industrial sectors to the stress-life (S-N) analysis of 'life-limited' or 'safe-life' components. A comparison of the fatigue design standards for 6 industrial sectors identified that the conservatism approaches are highly inconsistent when comparing the areas of variability and uncertainty accounted for along with the conservatism magnitude and method of application. Through the use of a case-study based on the SAE keyhole benchmark and 4340 steel S-N data, the industrial sector which introduces the greatest reduction of a component life-limit was identified as the nuclear sector. The results of the case-study also highlighted that conservatism applied to account for scatter in S-N data currently provides the greatest contribution to the reduction of component life-limits.

The objective of this research work is to reproduce in a test specimen, the fatigue failure that occurs in a damaged section of a structure. There is a structural problem, that is, the presence of a fracture at a certain point in the structure of the bus, starting at this point and growing progressively, causing damage. The steps of a methodology were applied to physically reproduce the fatigue failure in a representative specimen of a section of the bus structure, where the failure is located and up to the instrumentation of the testing machine and performance of the fatigue test. Subsequently, the results are analyzed and conclusions are made based on the results obtained in the laboratory test.

“…Fu et al [8] performed several fatigue tests on the U-rib-to-deck weld, the results demonstrated that the fatigue life of this detail can be extended with increasing penetration rate. Although the fatigue test method has been widely adopted in fatigue analysis, it has the disadvantages of harsh condition requirements, long test periods, high test costs, and potential safety problems [9]. The numerical simulation validated through experiments increasingly provides a reasonable performance assessment for structural fatigue.…”
