Duration: 24 months
Raw salary: 3000 € per month (roughly 2400 € per month, after tax removal)
How to apply: email a CV and motivation letter, as well as a reference letter from the PhD supervisor to S. Thuillier sandrine.thuillier@univ-ubs.fr and H. Laurent herve.laurent@univubs.fr

The aim of the post-doc is the experimental characterization and validation of forming limit curves at warm temperatures of aluminium alloys. A first part is dedicated to the mechanical design of an instrumented device dedicated to the characterization of the formability of aluminium alloys, under controlled conditions of temperature (in the range below 300°C), mechanical loading and friction. This part is a challenging one and should lead to the development of an original and reliable device. Data post-treatment is an essential step to obtain reproducible and reliable information and is based on a mixed experimental-numerical approach of the stress state and the sheet curvature [7]. Finally, a validation step should be performed with a dedicated device at warm temperature, already developed at IRDL [8]. Good and failed parts should be obtained, to validate the forming criterion. The thermo-mechanical numerical simulation of this process should represent faithfully these different cases, based on the experimental forming limit curves.
Diffusion of the results is very important, with the writing down of articles (in English) in
scientific journals and the presentation at international conferences is planned during the postdoc (like Esaform and IDDRG conferences).

Background of the candidate: mechanics of materials, numerical simulations with Abaqus, constitutive equations, forming process, experimental mechanics.
