Ultrasonic impact peening for the surface properties’ management
B.N. Mordyuk,G.I. Prokopenko +1 more
TL;DR: In this paper, an ultrasonic impact peening (UIP) technique is demonstrated to increase the fatigue durability of metallic materials due to the surface nanocrystallization and hardening process provided for severe plastic deformation of surface via multiple impacts of high velocity impact pins.

Fatigue behavior of a low-alloy steel with nanostructured surface obtained by severe shot peening
Sara Bagherifard,Mario Guagliano +1 more
TL;DR: In this article, severe shot peening aimed to generate a nanograined layer over specimens' surface has been applied by means of standard air blast equipment but using peening parameters essentially different from typical ones.

Predicting the effects of material properties gradient and residual stresses on the bending fatigue strength of induction hardened aeronautical gears
TL;DR: In this paper, an experimental methodology to characterize complex parts presenting various gradients using aeronautical induction surface hardened spur gears is proposed for the prediction of the bending endurance limit, taking into account residual stresses, microstructure variations, and surface roughness.

Analytical modelling for residual stresses produced by shot peening
TL;DR: In this article, an analytical model for the residual stresses formed during the shot peening process is analyzed, and two modifications are adopted: the hertzian pressure is considered as a dynamic load and the Ramberg-Osgood and/or Ludwick constitutive models of the stress curve is adopted to describe the plastic behaviour of the target material.

An evaluation of shot peening, residual stress and stress relaxation on the fatigue life of AISI 4340 steel
TL;DR: In this article, the authors evaluated the fatigue life of AISI 4340 steel, used in landing gear, under four shot peening conditions and found that relaxation of the residual stress field occurred due to the fatigue process.

Residual stress distributions and their influence on fatigue lifetimes
G. A. Webster,A.N. Ezeilo +1 more
TL;DR: In this paper, a non-destructive method for measuring residual stresses in structural engineering components is described. But the method is not suitable for the analysis of the residual stress distributions introduced by welding and the beneficial stresses produced by autofrettage, cold hole expansion and shot peening.

Investigation of residual stress relaxation under cyclic load
TL;DR: In this article, an analytical model is proposed for estimation of residual stress relaxation, considering the magnitude and distribution of the residual stress, the degree of cold working required, the applied alternating and mean stresses, and the number of applied loading cycles.

Relating Almen intensity to residual stresses induced by shot peening: a numerical approach
TL;DR: In this paper, a finite element to predict the residual stresses induced by shot peening in a metal part and to relate these stresses to Almen intensity is proposed; the aim is to provide the designer with a useful tool with which to choose the optimal treatment parameters with respect to the mechanical behaviour of the peened parts.
