Abstract:
Compressive residual stresses (CRS) are beneficial for enhancing the fatigue life of metal components. Shot Peening (SP) is an industrial cold working process that is applied to induce a field of CRS and modify the mechanical properties of the metal component. The SP process involves impacting a surface with tiny shots with forces sufficient to create plastic deformation. The process is governed by a number of important parameters such as the shot size, angle of attack, initial velocity, mass flow rate and the distance from the shot nozzle to the surface being peened. The relationship between

This thesis was performed at Scania CV AB and aimed to optimize the effect of shot peening in order to increase the bending fatigue limit of planetary gears. In this project three parameters affecting the performance of the shot peening were examined in more detail, specifically the hardness of the shot peening media, the hardness of the material and the amount retained austenite. Shot peening and measurements were performed on carburized gears consisting of ss 92506 steel. In order to find out how the fatigue limit is affected by the material hardness, a number of gears were tempered whereas

Abstract:
It has been well established that most fatigue cracks initiate from stress concentration sites found on the surfaces of components subject to cyclic fatigue loading. The introduction of residual compressive stresses into the surface layers of components, through various means including shot peening and laser shock peening, can result in local residual compressive stresses which provide a resistance to both crack initiation and propagation, thus leading to an increase in the fatigue life of the components.

Abstract:
Shot peening is a surface enhancement process used to improve the fatigue strength of metals by introducing beneficial compressive residual stresses on the surface. Shot peening is widely used in a number of industrial applications, including gas turbine engines. However, the fatigue life improvement gained via shot peening is not explicitly accounted for in current engine components life prediction processes. Therefore, there is a significant potential for increasing the predicted damage tolerance capabilities of engine components if beneficial residual stress considerations are incorporated

Shot peening is a cold working mechanical deformation process consisting of bombarding a metallic surface with small spherical media, called shots, at velocities commonly in the range of 10 to 100 m/s. Upon impact, the shots generate a near-surface deformed layer containing local hardening as well as compressive residual stresses, resulting in an improved fatigue resistance. However, the dependence of shot velocity and percentage of the total area covered by shot impacts on the surface modification introduced by shot peening are not well understood.The hardness and residual stress profiles ben

Although initiation was early, propagation through the peened surface layers was retarded by the residual compressive stresses introduced by the peening treatment; this retardation being greatest at a depth corresponding to that of the peak residual compressive stress.

Abstract:
Several major algorithmic and modelling aspects of the discrete element method are presented, with particular effort made to establish a general framework for the combined finite/discrete element simulation of shot peening and peen forming processes. On the basis of a general review of the contact detection algorithms, the alternating digital tree (ADT) and the augmented spatial digital tree (ASDT) are presented as examples of tree based search algorithms; whilst the dynamic cell based search algorithm is presented as an example of cell/grid based search algorithms. Extensive numerical tests a

Abstract:
Shot peening is a cold-working surface treatment, basically consisting in pelting the surface of the to-be-treated component with a high number of small hard particles blown at relatively high velocity. This causes the plasticization of the surface layer of the substrate, and the generation of a compressive residual stress field beneath the component surface. The surface topology modification can be beneficial for coating adhesion, and the work hardening enhances the fretting resistance of components, but the most commonly appreciated advantage of the process is the increased fatigue resistanc

Abstract:
In this study, residual stresses introduced via application of shot peening on the raceways of bearing rings and their effect on the fatigue life was investigated experimentally. For improvement of residual compressive stress state, shot peening operation with different parameters was utilized. Residual stress measurements were conducted via X-ray diffraction technique. Optimization of residual stress state during the production of ball bearings is the main target of this study. Process parameters for shot peening and super-finishing were studied for determination of the parameters that induce

Abstract:
Surface treatments used to improve the life of a material known as peening are already extensively used in industry. The main aim of peening is to introduce compressive resiudal stress to the surface and subsurface of a metallic material, however literature also includes a number of microstructural and mechanical effects that peening introduces to a material when the compressive residual stress is established. The aim of this dissertation is compare and contrast the mechanical and microstructural effects of a current industrial peening method called shot peening, with three new increasingly co
