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 کاملStudy and Simulation of Shot peening Effect on Fatigue Life of a Powder Forged Connecting rod
Shot peening applies a residual compressive stress field (RCSF) on the surface of parts. It also shifts “crack nucleation sites” to sub-surface locations. A nondestructive method of measuring the stresses, Sin2ψ was utilized here and the stress values introduced to Ansys software. For this purpose, uniform stress in all directions was applied on the con rod. Loading on the rod in Ansys had thre...
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 کاملEffect of Shot Peening on the Fatigue Behaviour of Cast Magnesium A 8
Shot peening is known to improve the fatigue performance of structural metallic materials. The improvement in fatigue life is derived primarily from compressive residual stresses that are introduced into the near-surface of the components and which hinder crack initiation and growth. Magnesium alloys are finding increasing use in automotive applications, but their relatively low strength means ...
