Ecole Polytechnique and McGill are seeking two PhD candidates for a large project aiming at understanding the effects of shot peening on the fatigue lives of aerospace components. The project involves 8 PhD students that will be working in close collaboration. The project is co-funded by the Canadian goverment and 5 leading aerospace companies located in Montréal. Some projects involve internships at these companies.

We are seeking two students for the following projects:

Shot peening for fatigue life improvement

The intention of shot peening is ultimately to alter the mechanical properties of a given surface. By hitting the surface with controlled shot the surface will deform plastically. Proper Instrumentation will play a vital factor in achieving reliable and intended results.

Shot peening is a process by which a substrate is impacted with round metal, glass or ceramic beads, also known as shot, at a force intended to create plasticity on the surface. The characteristics present prior to and after the peening process provides vital information to better the understanding and control of the process. Among many others, surface roughness and dimple coverage area left by the shot, are of particular interest.
