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 were used and stronger than if a

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 for the design and sustainab

Considerable steps to assess the structural capability of laser directed energy deposition (DED) aim to determine the viability of repair processes for integrally bladed rotors (IBRs). Two laser DED processes are under investigation in this study: wi

The push for low cost and higher performance/efficient turbine engines has introduced a demand for novel technologies to improve robustness to vibrations resulting in high cycle fatigue (HCF). There have been many proposed solutions to this, some pas

One major benefit of Additive Manufacturing is parts counts reduction. Several formerly distinct parts can be printed as one unit, reducing cost and weight. However, the interface between parts is often a major source of vibration damping, so elimina
