The requested funding for the proposed NSERC Engage project will allow the principal investigator, theindustrial partner (Meridian Lightweight Technologies), and Highly Qualified Personnel to investigate anddevelop engineering models of the self-piercing riveting (SPR) system to join Magnesium components to otherMagnesium components or dissimilar metals. This collaborative investigation is necessary due to challengesand lack of success which the industrial partner has had in achieving SPR for Magnesium components.Investigations will be completed, in a collaborative effort between the academic research team and theindustrial partner, to experimentally assess the mechanical material behaviour of base SPR materials.Additionally, in a similar approach, efforts will be undertaken to investigate deformation and mechanicalbehaviour of the SPR components during the riveting process.Information from the experimental portion of this project will be used to develop and validate finite elementmodels of the SPR system. This model will then be further used by the academic research team to exploredesign modifications to improve and enhance the joining of components, specifically components involvingMagnesium alloys, using the SPR method.It is anticipated that the proposed NSERC Engage project will result in the development of information whichwill allow the industrial partner to implement a SPR into challenging lightweight materials, potentiallyresulting in Meridian Lightweight Technologies becoming a world leader in joining of lightweight materials fornumerous practical applications.
