“…As the first case study and to illustrate the strength of the present approach, the residual stress and eigenstrain profile determined by variational inverse eigenstrain analysis is examined. The aluminum alloy thick coupon with effective elastic modulus of E ɶ =103 GPa has dimensions of 150×50×4 mm and in tests is peened to full coverage using typical 0.5 mm shots (Levers and Prior, 1998). The residual stress and eigenstrain profile determined by Korsunsky (2005) utilizing variational inverse eigenstrain analysis are also shown in Fig.…”

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.

“…With the appearances of powerful finite element software such as ABAQUS, ANSYS and NASTRAN, attention was focused on numerical simulation of shot peening process [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Such a simulation method provides a cheap and easy way to study the dynamic impact of a shot with high velocity, the double non-linearity of the problem due to the contact of two bodies and the elastic-plastic behaviour of the target, etc.…”

“…It is worth noting that although above works [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] provide a powerful method for establishing quantitative relationships between shot and target parameters and residual stress characteristics, FE methods could not still simulate a stream of discrete shots impacting on a target. Recently, discrete element (DE) method has been adopted to simulate shot peening process by Han et al [39][40][41].…”

-It is very significant to investigate the shot peening mechanism in ensuring a good resistance to fatigue and stress corrosion. This paper reviews the recent advancements in shot peening process. Emphasis is put on the application of numerical simulation techniques and finite element method in residual stress prediction during shot peening process. Different methods related to shot peening modelling and prediction of plastic deformation and surface integrity are reviewed. Some key issues such as algorithms and simulation procedures are discussed.

“…Compared with conventional plastic forming, creep aging enjoys high forming accuracy and repeatibility, hence reducing the risk of materials cracking in processing and residual stress of components [3,4]. Therefore, scholars have conducted in-depth research on the resilience prediction and performance of creep aging forming.…”

Abstract:Normal temperature tensile and fatigue tests were adopted to test the mechanical performance and fatigue life of 2524 aluminum alloy under the three states of T3, artificial aging, and creep aging, and scanning electron microscope and transmission electron microscope were also used to observe the fatigue fracture morphology and aging precipitation features of the alloy under the above three states. Results showed that the alloy treated by creep aging can obtain higher fatigue life, but that treated by artificial aging is lower than T3; T3 alloy is mainly dominated by GPB region. Meanwhile, the crystal boundary displays continuously distributed fine precipitated phases; after artificial aging and creep aging treatment, a large amount of needle-shaped S phases precipitate inside the alloy, while there are wide precipitated phases at the crystal boundary. Wide precipitation free zones appear at the crystal boundary of artificial-aging samples, but precipitation free zones at the alloy crystal boundary of creep aging become narrower and even disappear. It can be seen that creep aging can change the precipitation features of the alloy and improve its fatigue life.
