Strain-life parameters
WebThe strain life criterion is typically used for the low cycle fatigue; for example, the material fatigue due to the thermal cycle of structure. The stress level is higher and the number of … WebFatigue models using the strain-life method do not show exact conformity with the empirical results. Therefore, the use of the mean-stress correction approach is to be evaluated, with a particular focus on mild and higher-strength steel. The influence of the ductility parameters will be studied. A potential favorable development of structural steels with regard to …

Web4 Oct 2024 · Based on this study, ‘modified universal slopes method’ for steels, ‘uniform material law’ for aluminum alloys and ‘Mitchell’s method’ for titanium alloys are suggested as the best methods to approximate strain life parameters of these respective materials. Also, Roessle-Fatemi method for steel is suggested in the absence of %RA data from UTS. Web3 Nov 2024 · A series of numerical simulations was carried out on a 53-element steel truss model to study the availability and numerical stability of the method. The effects of different initial values, numbers of strain tests, and locations of the strain test as well as the number of unknown parameters on the identification results were studied.
