The experienced researcher Bernardete Coelho, doctor in Mechanical Engineering from the University of Aveiro (Portugal), aims at leading research activities on the numerical modelling of the thermo-mechanical behaviour of β-metastable titanium alloys. Such activities will be carried out in Université Bretagne Sud (France) under the supervision of Prof. Sandrine Thuillier. <br/>Advanced materials such as titanium alloys are considered as technological key enablers in societal challenges and a key factor in technological solutions, as they determine the process, the mechanical properties and the service life of an object. Regarding β-titanium alloys, they are more and more used in the biomedical and aeronautic fields and the modelling of their thermo-mechanical behaviour will become an enabling technology in order to perform forming at warm and elevated temperatures. Given the huge interest in the thermo-mechanical behaviour of lightweight β-titanium alloys, one objective of this project consists in its investigation and numerical modelling over a large range of temperatures. It is also intended to include the modelling of the occurrence of plastic instabilities in β-titanium alloys, for a biphasic material, i.e. titanium molybdenum with several compositions as well as an industrial material. Moreover, the technological part of this project aims to validate the thermo-mechanical models to the case of hot forming of a β-titanium alloy. Then, the final objective of this project is to perform a fast eco-audit, using eco-indicators, for different scenarios including hot forming and heat treatment for β-titanium alloys. Additionally, a business plan for a promising application will be developed. As a global overview, this project deals with the virtual forming and mechanical design of parts made out of β-titanium alloys for a large range of compositions, based on the modelling of the thermo-mechanical properties (up to rupture) of such alloys in a large range of temperatures.
