Multiaxial fatigue reliability analysis of railroad wheels
A general methodology for fatigue reliability degradation of railroad wheels is proposed in this paper. Both fatigue crack initiation and crack propagation life are included in the proposed methodology using previously developed multiaxial fatigue models by the same authors. A response surface method in conjunction with design of experiments is used to develop a closed form approximation of the...
متن کاملPrediction of Fatigue Life in Notched Specimens Using Multiaxial Fatigue Criteria
In this research, the effects of notch shape on the fatigue strength of 2024-T3 aluminum alloy notched specimens have been studied using experimental and multiaxial fatigue analysis. For this purpose, four set of specimens with different notch shape were prepared and then fatigue tests were carried out at various cyclic longitudinal load levels. Load controlled fatigue tests of mentioned specim...
متن کاملMultiaxial Fatigue Analysis in a High-speed Microgenerator Rotor Shaft
Fatigue evaluation is one of the most concerning issue in the design of mechanical parts subject to alternative forces. Fatigue life estimation is more complicated when loads act on different axes. This paper shows the stress analysis result of the steel shaft of a high-speed microgenerator rotor with 47750 rpm and 100kW which has been carried out with analytical stress formulation. The shaft i...
متن کاملMultiaxial high-cycle fatigue criterion and life prediction for metals
A new high-cycle fatigue criterion based on the critical plane approach is proposed in this paper. Unlike most of the other multiaxial fatigue criteria based on the critical plane approach, the critical plane is directly correlated with the fatigue fracture plane. The proposed criterion has a wide range of applicability from very ductile metals to extremely brittle metals. Mean stress effect is...
