What is it about?
In this work we investigate how a fatigue life improvement technique (shot peening) affects fatigue life in leaf springs. Fatigue is the major failure mode of these components, which are essential for suspensions in large vehicles (like trucks, for example).

Why is it important?
Although shot peening is know in industry for a long time, there is surprisingly few academic works about the process, there are hypotheses justifying how the repeated high velocity impact of small spheres n the component surface could affect fatigue life. In this work we show that the picture is not so straightforward as assumed by these hypotheses.
Perspectives
This is another great collaboration with a brilliant (former) student. This time Dr. Scuracchio, who still works in related issues in the industry and was able to deliver a nice piece of academic work in a technology related issue.
