This surface enhancement method generates beneficial modifications like superficial compressive residual stresses that are known to delay crack initiation and propagation. In the same way, work hardening is also introduced at the surface of the part during shot peening and can have a significant influence on fatigue crack initiation. Taking this parameter into account in the fatigue design of parts, in addition to the residual stresses, is a real challenge to be the most predictive. One possibility for this is to be able to predict it during the modeling of the shot peening process. In the present work, various peening conditions are considered in order to be able to propose a model able to account for the influence of coverage and Almen intensity on residual stresses and work hardening. The studied material is Inconel 718, commonly used for aeronautical parts. The X-ray diffraction method is used to obtain the in-depth residual stress and work hardening profiles. A three-dimensional numerical model is proposed to predict these quantities. Efforts are made to consider all recent advances in three-dimensional simulation of the process, in terms of coverage assessment, shot and treated part modeling. The numerical results are compared to the experimentally measured residual stresses and work hardening.<\/p>\n<p><a class=\"btn-tec black\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0020768323000173\" target=\"_blank\" rel=\"noopener\">Link to publication<\/a><\/p>\n<p>Key words: Shot peeningFinite-element modelResidual stressesWork hardeningInconel 718<\/p>\n<p><em><small>Originally published at International Journal of Solids and Structures (Volume 264, 1 March 2023, 112120)<br \/>\nBy J.P.
