TL;DR: In this article, a detailed study on the fatigue crack growth behavior in a generic aerofoil specimen of Ti-6Al-4V alloy treated by laser shock peening (LSP) prior to FOD, using both experimental and numerical approaches, is presented.

TL;DR: In this paper, microstructural evolutions of electron beam melted (EBM) Ti-6Al-4V alloy modified via laser shock peening (LSP) were measured before and after LSP.

TL;DR: In this paper, the authors investigated whether the near surface residual stresses induced by surface treatments like shot peening are balanced by low-level tensile residual stresses all over the core of the specimen or by relatively high residual stresses in a thin layer adjacent to the surface layer.

TL;DR: In this paper, laser shock peening was performed on a 316 L stainless steel part fabricated by Selective Laser Melting (SLM) to increase the stored energy in the material but does not lead to measurable grain refinement.

TL;DR: Shot peening of thin edges of workpieces which are subject to deformation damage by direct impacts is accomplished by rotating the workpiece edge near centerline through a particular angle measured from the normal to the shot streamline.
Abstract: Shot peening of thin edges of workpieces which are subject to deformation damage by direct impacts is accomplished by rotating the workpiece edge near centerline through a particular angle measured from the normal to the shot streamline. The angle is sufficient to cause oblique blows on the centerline of the edge, but insufficient to cause direct impacts. Compressive stresses by the oblique blows provide residual compressive stresses along the centerline to the desired depth. The angle is calcuable from the edge radius, the depth of stressing desired at the centerline, and the depth of stressing produced by shot at a reference location. Oscillatory rotation is preferably used to obtain even peening.
