High-frequency mechanical impact (HFMI) is a post-weld treatment method which substantially enhances the fatigue strength of steel weldments. As such, the method enables a more efficient design of bridges, where fatigue is often the governing limit s

Structural design of bridges in Europe should be carried out in accordance with Eurocode regulations. However, there is no guideline demonstrating how the fatigue design is to be conducted when high-frequency mechanical impact (HFMI) is used to enhan

High-Frequency Mechanical Impact (HFMI) is one of the newest post-weld treatment methods that can be used to repair cracks in welded structures. The main effect of this method is to extend the fatigue life by putting the cracks under compression. Lin

Fatigue is one of the most detrimental problems that often limit the service life of steel bridges. Because of that, different post-weld treatment methods have been studied to extend the fatigue life and repair any existing cracks resulted from the t

High-Frequency Mechanical Impact (HFMI) is a rather new post-weld-treatment method that has shown interesting fatigue life enhancement capabilities. The influence on material behaviour needs, however, to be investigated more to reach a full understan

Fatigue cracks have appeared as a significant issue for joints and connections in existing steel structures in the last decades. Therefore, those are a major inspection and maintenance matter for any steel structure's operator. This emphasises the im
