Abstract: 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 ...

Abstract: Criteria for assessing high cycle fatigue (HCF) capability are important for transitioning additive repair technologies to turbine engines. By studying the fatigue results of two additive repair technologies on Titanium ...

Abstract: The fatigue life behavior and internal surface conditions of inherently damped additive manufactured (AM) specimens subjected to vibration bending are under investigation. This study supports research that demonstrated 95% ...

Abstract: A recently developed high cycle fatigue (HCF) acceptance criteria demonstrates effectiveness in assessing the viability of two laser directed energy deposition (DED) repair processes on titanium 6Al4V (Ti 6Al4V) fan blades. ...

Abstract: The repeatability of an additive manufacturing (AM) process that fabricates a unique specimen with inherent damping capability is explored. A laser powder bed fusion (LPBF) technique is used to additively manufacture nickel ...
