Finite element modelling of shot peening process- A progress overview
It is very significant to investigate the shot peening mechanism in ensuring a good resistance to fatigue and stress corrosion. This paper reviews the recent advancements in shot peening process. Emphasis is put on the application of numerical simulation techniques and finite element method in residual stress prediction during shot peening process. Different methods related to shot peening mode...
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...
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 کاملShot Peening Optimization using the Discrete Element Method
The aim of this study is to develop a Discrete Element Model (DEM) capable of simulating the main shot peening (SP) processes of industrial interest. By means of this model, shot shot interaction, shot target interaction and the overall shot flow were investigated in detail with limited computational effort. A new technique to dynamically change the coefficient of restitution (CoR) for repeated...
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 ...
