TL;DR: In this article, an elastic predictive approach is described based on arrest of short cracks propagating from a notch, which is an idealisation of the damage, and extended for the case of combined cycle loading, where the blade experiences a combination of centrifugal and vibrational loading.

TL;DR: In this paper, a gas gun was used to introduce the damage by firing a hardened steel cube "point first" and the residual stresses were evaluated using two different experimental techniques involving X-ray diffraction: laboratory low energy monochromatic stress measurement, and high energy white beam synchrotron stress measurement.
52 citations
TL;DR: In this article, the authors used the finite element method to analyze the leading edge of the turbine blade of an aircraft turbine and compared the results with the experimental and analytical data at the crater base.

TL;DR: Low plasticity burnishing (LPB) as discussed by the authors provides thermally stable compression and can be performed in conventional machine shop environments on CNC machine tools, enabling the extension of component service lives fatigue limited by various damage mechanisms including foreign object damage (FOD), corrosion fatigue, pitting, and fretting.
Abstract: Surface enhancement technologies such as shot peening (SP), laser shock peening (LSP), and low plasticity burnishing (LPB) can provide substantial fatigue life improvement. However, to be effective, the compressive residual stresses that increase fatigue strength must be retained in service. LPB provides thermally stable compression and can be performed in conventional machine shop environments on CNC machine tools. LPB enables the extension of component service lives fatigue limited by various damage mechanisms including foreign object damage (FOD), corrosion fatigue, pitting, and fretting. The thermal and mechanical stability of the compressive layer are briefly reviewed. The LPB process, tooling, and control system are briefly described. Four representative applications are presented: thermal stability in IN718, improved damage tolerance in Ti-6-4 fan blades, mitigation of fretting fatigue damage in Ti-6-4, and improved corrosion fatigue in 17-4PH stainless steel.

TL;DR: In this paper, the research on high cycle fatigue (HCF) strength of TC11 titanium alloy after subjected to foreign object damage (FOD) was presented. And the results showed that the microscopic characteristics of damage area include smooth area, micro cracks, micro notches, shear bands and loss of material (LOM).
