Plastic deformation from peening induces a compressive residual stress on the treated surface which provides resistance to metal fatigue. Hence, peening is often used to extend the fatigue lives of welded components by reducing the effective tensile

By using Ultrasonic Peening the service-life of an offshore installation can be extended. Every floating installation will have weak spots in its structure, this is almost enivatble. We call these weak areas "fatigue hot-spots". In practice the fatig

Abstract The fatigue life extension procedure by ultrasonic peening uses FEA to assess the critical weld details and to define the location and extension of the areas to be treated. However, FEA models do not take into account variations in as-built
