Abstract: While integrally bladed rotors in turbine engines have multiple benefits, they are more susceptible to vibration and as a result, high cycle fatigue failure. In response, damping treatments such as viscoelastic layers, ...

Abstract: Centrifugal compressors have a critical impact on the performance of a jet engine and can be made out of aluminum, steel, or titanium alloy. However, if made out of Ti-6Al-4V, it would be more lightweight than if steel ...

Abstract: The aim of this paper is to provide a novel stochastic life prediction approach capable of predicting the total fatigue life of applied uniaxial stress states from a reduced dataset reliably and efficiently. A previously ...

Abstract: A modified experimental method using digital image correlation (DIC), a noncontact optical method for measuring full-field displacements and strains, is used to interrogate accumulated fatigue damage for low and high cycle ...

Abstract: This study applies a novel strain-energy based fatigue life prediction method to low cycle fatigue (LCF) data additive manufactured (AM) Inconel 718 round dog-bones, specifically focusing on cycles to failure less than ...

Abstract: Very high cycle fatigue (VHCF) data and experiments, 107–109 cycles to failure, have traditionally been both a cumbersome and costly task to perform. However, characterizing VHCF behavior of material systems is critical ...
