Controlled shot-peening is an operation which is used largely in the manufacture of mechanical parts. It should not be confused with sand blasting used in cleaning or descaling parts. Shot-peening is in fact a true machining operation which helps increase fatigue and stress corrosion resistance by creating beneficial residual surface stresses. The technique consists of propelling at high speed small beads of steel, cast iron. glass or cut wire against the part to be treated. The size of the…

The influence of partial surface shot peening on fatigue crack growth behaviour of a high-strength ferritic steel
The effects of partial surface shot peening on the fatigue crack growth behaviour of a ferritic steel have been experimentally investigated in this paper. Dog-bone specimens fabricated from
Ball-burnishing effect on deep residual stress on AISI 1038 and AA2017-T4
ABSTRACT Ball-burnishing induces compressive residual stresses on treated materials by the effect of plastic deformation. The result is an increase in the fatigue life of the treated part, retarding
A combined DEM-FEM numerical method for Shot Peening parameter optimisation
A novel combined DEM-FEM method for Shot Peening optimisation is presented, which provides a rapid method to investigate the effect of the peening parameters and the minimum area required to be modelled to realistically capture the field of residual stresses.
Experimental investigation of the strain rate dependence of SS2506 gear steel
hot peening is a surface treatment used to increase the fatigue strength of metallic components, for example gears, and it is of great interest to be able to model and simulate the effect of this t
