Side Effects of Shot Peening on Fatigue Crack Initiation Life
Shot peening beneficial effects on fatigue life of mechanical components are well known. However, there are some reports in the literature that indicate inappropriate shot peening parameters tend to reduce the fatigue life. It is therefore, the purpose of this study to find a logical quantitative justification for these observations. Using finite element method, a dynamic elastic-plastic simula...
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 کاملIncreased osteoblast function in vitro and in vivo through surface nanostructuring by ultrasonic shot peening
Surface topography has significant influence on good and fast osseointegration of biomedical implants. In this work, ultrasonic shot peening was conducted to modify titanium to produce nanograined (NG) surface. Its ability to induce new bone formation was evaluated using an in vivo animal model. We demonstrated that the NG surface enhanced osteoblast adhesion, proliferation, differentiation, an...
متن کاملLaser Peening Process and Its Impact on Materials Properties in Comparison with Shot Peening and Ultrasonic Impact Peening
The laser shock peening (LSP) process using a Q-switched pulsed laser beam for surface modification has been reviewed. The development of the LSP technique and its numerous advantages over the conventional shot peening (SP) such as better surface finish, higher depths of residual stress and uniform distribution of intensity were discussed. Similar comparison with ultrasonic impact peening (UIP)...
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 ...
