Abstract null null To revealing the role of unevenly microstructural rafting caused by stress gradient on the fatigue resistance of engineering parts made by single crystal (SC) Ni-based superalloys, a stress-control low cycle fatigue (LCF) experiments were performed at 980℃ with a 0.1 stress ratio of central-hole specimens that underwent different pre-rafting treatments. An image process algorithm and field emission scanning electron microscope (FE-SEM) were employed to given a quantitative des...

Abstract null null This study presents a strategy to estimate the extra cost due to start-up and shut-down of hydro turbines under high-cycle fatigue. The principle is to compare estimations of cumulated damages from three elementary sequences representing steady and transient regimes (start and stop cycles) of turbine runners, from in-situ strain measurements. Rainflow cycle-counting is used to extract stress cycles from these three sequences. Fatigue design curves are defined, taking into acco...

Abstract null null This paper deals with the notch fatigue behaviour and crack initiation life estimation in maraging steel fabricated by laser beam powder bed fusion under multiaxial loading. Tests are conducted in tubular geometries with lateral holes considering different normal stress to shear stress ratios and multiaxial loading levels. The cyclic stress-strain response at the notch-controlled process zone is simulated numerically using two alternative approaches: a generalised isotropic pl...

Abstract null null Extreme value (EV) statistics have been previously utilized to model the tails of distributions of computed Fatigue Indicator Parameters (FIPs) to provide a method of ranking microstructures in terms of resistance to fatigue crack formation under identical loading conditions. FIPs that capture the two primary transgranular mechanisms for fatigue crack formation and early stages of growth in bimodal Ti-6Al-4V are computed for cyclic strain-controlled loading conditions correspo...

Abstract null null Shape memory alloys are able to recover the initial shape even after a large deformation. The memory property is due to the ability to change the microstructure under a variation of the stress state or the temperature. The stress-strain curve is characterized by the presence of a stage where the slope of the curve sharply decreases and the initial microstructure transforms into a new one. In this work, an integrated microstructural-mechanical model is proposed for the equiatom...
