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 کاملNumerical and Experimental Evaluation of Residual Stress and Fatigue Strength of Steel CK35 in Shot Peening Process
In shot peening process the work piece surface is struck by a large number of balls and compressive residual stress is generated on the surface. So, mechanical properties such as fatigue strength, stress corrosion resistance, smooth shape and ... will improve. In this paper, the balls with a speed of 100 to 200 m/s were struck on the steel samples and fatigue strength compared with specimens wi...
متن کاملSurface Layer Analysis after Shot Peening by Barkhausen Noise Signal
In the paper there will be introduced method for relative determination of induced kinetic energy of hardened balls on treated surface, which was invented by J. Alemen. In our experimental work we were focused on measuring Barkhausen noise signals and comparison with microstructure, microhardness, and residual stress analysis of surface roughness. In process of shot peening there is occurrence ...
متن کاملSpatially Resolved Characterization of Residual Stress Induced by Micro Scale Laser Shock Peening(1501)
Single crystal Aluminum of (001) orientation were shock peened using laser beam of 12 micron diameter and observed with X-ray micro-diffraction techniques based on a synchrotron light source. The X-ray micro-diffraction affords micron level resolution as compared with conventional X-ray diffraction which has only mm level resolution. The asymmetric and broadened diffraction profiles registered ...
