Biography:

Prof. Lévesque held the Canada Research Chairs in multi-scale mechanics for the last ten years. His research focuses on bridging the gaps between the different length scales to predict the overall mechanical performance of materials and parts. He has applications in the shot peening field, as well as in the mechanics of composites, the manufacturing of composites as well as the additive manufacturing of composites. He develops both numerical and theoretical models, as well as experimental techniques to better understand materials behaviour at various length scales. He is currently the chairman of the International Scientific Committee for Shot Peening and the Head of the Mechanical Engineering Department at Polytechnique Montréal.

Abstract:

This talk will present the multi-scale approaches developed at the Laboratory for Multi-Scale Mechanics to predict the effects of shot peening in terms residual stresses, microstructural changes and surface characteristics, as well as the prediction of the effects of peen forming on the final shape of thin panels. The talk will feature both experimental methods and modelling techniques (finite element, discrete element), will look at the effect of the process at different length scales (from micrometer to the meter) and will deal with processes like conventional shot peening and vibratory peening.
