“…The effects of some parameters have been investigated in the simulation of a single impact with the FE method in [3,4]. For the multi-impact modeling, an analytical approach to determine the arc height induced by shot peening as well as a relationship between the arc height and the residual stress field is proposed in [5,6]. It can be deduced from the literature that the most important parameters in the USP process are the shot velocity and the peening coverage rate.…”

During a repair welding process, the ultrasonic shot peening (USP) process can be used as the final finishing step. The aim is to introduce compressive residual stresses on the surface of the welded area in order to prevent the occurrence of cracking. Although the numerical simulation method is able to predict the state of residual stress in the peened part, the 3D models of the real USP process, in which many successive and shifted impacts take place, is very delicate and costly in terms of computing time and memory space required. In this paper, we propose a method based first on the calculation of the averaged inelastic strain tensor in a local representative area, and second on the transfer of this inelastic strain field in order to simulate the USP process. Experiments, similar to the "Almen test", are performed on a thin plate of Inconel 600. Numerical results in terms of distortions and residual stresses are compared with the experimental data.

“…A remarkable set of publications could be found in the literature dedicated to the modeling of residual stress state of shot peening process utilizing different types of finite element modeling (Guagliano, 2001;Zimmermann et al, 2009;Gonzales et al, 2010), analytical methods (Shen and Atluri, 2006;Franchim et al, 2009;Miao et al, 2010) or experimental methods (Niku-Lari et al, 1985;Fathallah et al, 1998;Menig et al, 2001). However it is currently difficult and prohibitively time-consuming to measure the complete patterns of residual stresses throughout the most structural materials (Krawitz, 2011).…”

A modified stress function approach is developed here to reconstruct induced stress, residual stress and eigenstrain fields from limited experimental measurements. The present approach is successfully applied to three experimental measurements set in surface peened plates with shallow shot peening affected zone. The well-rehearsed advantage of the proposed approach is that it not only minimizes the deviation of measurements from its approximations but also will result in an inverse solution satisfying a full range of continuum mechanics requirements. Also, the effect of component thickness as a geometric parameter influencing the residual stress state is comprehensively studied. A key finding of present study is that the plate thickness has no influence on the maximum magnitude of eigenstrain profile and compressive residual stresses within the shot peening affected zone while having a great influence on the magnitude of tensile residual stress and the gradient of linear residual stresses present in deeper regions.

“…Shot peening has been extensively studied experimentally, analytically and numerically so that many controlling conditions, parameters, and applications have been identified [11][12][13][14][15][16][17][18][19][20][21][22][23]. A great many engineering components and parts contain a residual stress that usually originates from its manufacturing process.…”

A study of the residual stress induced by shot peening for an isotropic material based on Prager’s yield criterion for combined stresses

Prager developed a yield criterion for a generalized isotropic material that is more capable of predicting material behavior that occurs from combined loading. A less studied topic is the effect of combined loading on the residual stress state. The purpose of the present work is to develop a theoretical model for a residual stress based on Prager's relation and establish how the predictions are influenced. Prager's yield criterion which includes the third deviatoric invariant, J3, provides a way to estimate the influence J3 has on the residual stress. The analyzed residual stress originates from shot peening because much experimental data exists to compare and validate the theoretical results.
