Study 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 کاملExperimental Study on Ultrasonic Shot Peening Forming and Surface Properties of AALY12
Ultrasonic shot peening (USP) studied. Several parameters (arc heights, surface roughness topography and micro hardness) with different parameters were measured. The research proposes curvature of shot peened sheet increases with time decreasing, while increases with pin diameter increasing, and curvature reaches a saturation level after a specific electric current. An empirical model of the re...
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 کاملShot peening simulation using discrete and finite element methods
Modeling shot peening process is very complex as it involves the interaction of metallic surfaces with a large number of shots of very small diameter. Conventionally such problems are solved using the finite element software (such as ABAQUS) to predict the stresses and strains. However, the number of shots involved and the number of elements required in a real-life components for a 100% coverag...
متن کاملFinite Element Simulation of Shot Peening and Stress Peen Forming
Shot peening is widely used to improve fatigue life of the metal component. It can also induce the distortion of thin component, which is called peen forming and is widely used for shaping aircraft wing skin. Shot peening surface coverage, intensity and saturation are important shot peening control parameters and have greatly influence on shot peening and peen forming results. Due to the insuff...
