An Analytical Model for Shot-Peening Induced Residual Stresses
To improve the fatigue life of metallic components, especially in aerospace industry, shot peening is widely used. There is a demand for the advancement of numerical algorithms and methodologies for the estimation of residual stresses due to shot peening. This paper describes an analytical model to simulate the shot peening process and to estimate the residual stress field in the surface layer....
متن کاملEffect of Residual Stresses on Fatigue Strength of Severely Surface Deformed Steels by Shot Peening
The compressive stress distribution below the specimen surface of severely surface deformed steels by shot peening was investigated by using laboratory X-rays and high-energy X-rays from a synchrotron radiation source, SPring-8 in the Japan Synchrotron Radiation Research Institute. Medium carbon steel plates were heat treated in two different conditions. The Vickers hardness of material-A and B...
متن کاملA New Procedure for the Evaluation of Residual Stresses by the Hole Drilling Method Based on Newton-raphson Technique
The hole drilling method is one of the most used semi-destructive techniques for residual stress analysis of mechanical parts. In the presence of non-uniform residual stresses, the stress field can be determined from the measured relaxed strains using several methods, but the most used is the so called integral method. This method is characterized by some simplifications that lead to approximat...
متن کاملInfluence of Shot Peening Parameters on Residual Stresses in Flake and Vermicular Cast Irons
Test samples of grey and compacted graphite cast irons with pearlitic matrix were shotpeened to different surface conditions using twelve different combinations of shot size, peening intensity and peening coverage percentage. Relatively high surface compressive residual stresses varying between 245 to 565 MPa were observed and the compressive residual stresses reached a depth between 280 μm and...
متن کاملQuantification of Residual Stresses in the Weld by the Hole-drilling Method
Many failures of supporting structures or machines are not caused only by stresses that are invoked by loading, but they often result due to residual stresses. Time needed for reparation of equipment and production losses are important factors, but much more serious are possible injuries or death of people. Residual stresses occur also in the structures without loadings. They arise mostly due t...
