RESIDUAL STRENGTH APPROACH TO FATIGUE DESIGN AND ANALYSIS

Standard fatigue design practices are frequently based on the endurance of a component, that is the number of cycles to cause fracture of the component at the peak of the cyclic load. These procedures, however, are of little use in assessing the effect of overloads on the strength of structures that have been subjected to overloads, or in determining the performance of an existing structure prior to fracture through fatigue. The authors develop a fatigue methodology that is based on the residual strength of a component during cyclic loading, rather than endurance. The procedure is valuable in assessing the remaining strength and endurance of a structure subjected to cyclic loads and the effect of remedial work on the structure. This more accurate design procedure is based on the true performance of the structure.
