“…In their work, a DE representation of shot was adopted and different contact interaction laws for shot-target collision were extensively studied with special attention given to the proper selection of the parameter values involved. Besides, the modelling of the residual stresses on crack propagation and on the stress relief during load service was also performed [42][43][44][45].…”

-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.

“…However, modeling of the shot-peening process is often very difficult. Earlier work was conducted using finite-element analysis [4][5][6][7], and simplified analytical modeling [8]. It can also be difficult to measure complete patterns of residual stresses throughout the component and only limited measurements are made.…”

“…Unlike the SPD process such as shot peening and deep rolling that only introduce compressive residual stress at the surface [19][20][21], ECAR causes the different surface residual stress as the stress at the bottom surface is tensile. Therefore this distribution has to be considered in applying the ECARed sheet in service condition or latter process.…”

The layer removal technique and the x-ray diffraction method have been employed to evaluate the residual stresses through the thickness of aluminium alloy 5083 processed by equal channel angular rolling (ECAR). ECAR is a severe plastic deformation process that introduces shear deformation to sheet metals. The process has been completed on 2 mm thick strips passed three times through die channels in a continuous manner. In this work, the profile of residual stresses was quantitatively determined. It was observed that after ECAR process, the residual stress magnitudes were changed from approximately zero in annealed condition up to half of the yield strength value of ECARed samples. The distribution of the residual stresses was found to be non-uniform through the thickness and the ECARed sample was compressive at the top surface while it was tensile at the bottom surface.2 Keywords: Non-ferros metals and alloys (A), X-ray analysis (G), Elastic behaviour (F).
