PhD thesis objectives
While the metal forming community have fair hindsight of the phenomena linked to bulk material forming, such as plasticity or thermal effects, one of the key points of a process performance is friction. It is a complex phenomenon which remains not well mastered, and may lead to micro-cracks in the formed parts, fatigue fracture of the forming tools and of the manufactured parts in service, or local, microstructure transformations that could dramatically change the expected behaviour of the tools and the formed parts. Studying such local phenomena on reduced regions may lead to make assumptions on how these local regions are affected by the global loadings on the part or process, which may change with the forming or service scheme.
Desired skills and knowledge of the PhD student
Use of commercial finite element soKwares (e.g. Abaqus, Ansys, LS-Dyna), general knowledge on material behaviour and Finite Element Method, programming languages (Matlab, C++).
Knowledge on Lagrange multipliers / coupling techniques would be a plus.
