AbstractIn this thesis we propose to study the fundamental question of microscopic dry friction between metallic rough surfaces by taking into account the behaviour of the relevant material as well as the thermo-mechanical coupling. This innovative study is based on the unique combination of framing expertise in crystalline plasticity, roughness modeling, thermo-mechanical experimental techniques, and advanced numerical methods of multi-physical coupling for contact problems.
ProfileTo be admitted to a doctorate, the candidate must hold a national master's degree or another diploma conferring the master's degree (engineering diploma, equivalent foreign diploma, etc.), following a course of training establishing his research aptitude.
Applicants will be selected after interview before a jury assessing their research aptitude and the adequacy of their training and knowledge with the proposed thesis subject. Strong scientific knowledge, a first research experience (internship 4 months minimum), a strong motivation for research, a good level in English will be required (minimum B2).
The application must include:
a motivation letter including the candidate's professional project
a detailed curriculum vitae mentioning studies, research internships carried out, diplomas with date obtained, professional experience, research axes envisaged
a transcript of marks from the previous course (engineer and / or master cycle)
one or more letters of recommendation ...
a certificate of English level.
for a non-French speaking student, an A2 / B1 level in French (European standard) is recommended when entering a doctorate
for students who do not hold a national research masters diploma, all documents attesting to the students qualifications in research training (research internship certificates with summary of the dissertation, recommendations, publications, etc.)
a copy of identity card or passport

The documents in pdf format must be sent to no later than June 8
