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 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 کاملCorrosion Properties of 34CrMo4 Steel Modified by Shot Peening
A nanocrystalline layer was prepared on the surface of 34CrMo4 steel by time controlling shot peening (SP, i.e., 1, 5, 10, and 20 minutes). Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) analysis, and transmission electron microscope (TEM) were applied to analyze the surface, cross-sections, and grain size of the specimens before and after SP. The electrochemical c...
متن کاملShot Peening as an Alternative to Fatigue Life Improvement of CK45 Steel Coated with an Electroless Ni-Cu-P
The effect of an electroless Ni-Cu-P coating on the fatigue behavior of quenched and tempered CK45 steel has been investigated. The fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. The results indicate that plating of the base steel leads to a fatigue life reduction. The d...
متن کاملMe5656 - Mechanics of Contact & Lubrication Term Project Shot Peening Process
Shot peening is a process where compressive residual stresses are generated at the surface of the processed part by impacting small hard particles to the surface in order to increase the fatigue resistance of the part. In this work, a general literature survey of shot peening process is presented. Survey is mainly focused on mechanics and numerical simulation of the process. Effects of various ...
