Abstract
The fatigue failure is responsible for the majority of products failures. Therefore, this work gathered many published papers to promote a discussion and an analysis about the effectiveness of the use of the shot peening over the fatigue resistance enhancement of the material. Thus, it was analyzed the effects of the process over the materials conditions changings. The process was evaluated by the Almen intensity parameter and the materials condition by their mechanical properties and residual stresses. It was concluded that the effectiveness of the process depends more on the material state than the process parameters. In addition, such observations were obtained from papers that tested metallic materials, however it is possible to expand them to others kind of materials since these materials behave similar to metallic materials.
