Description of the thesis topic
An earthquake occurs when a seismic fault experiences a stick-slip transition. The objective of the PhD is to study the fundamental mechanisms governing the dynamics of a fault based on model systems, in the laboratory. The approach is mainly experimental and the project is at the interface of the physics of friction, fracture and geophysics.
Despite considerable efforts by physicists, geophysicists and engineers, a fundamental understanding of friction eludes us. Recent work has revealed that the sliding of solid surfaces is governed by the propagation of an interfacial fracture. We will focus on the case of frictional systems in the presence of interfacial disorder: granular material, roughness. Experimental techniques will include rapid imaging, strain measurements and image processing.
We are looking for a candidate who is particularly motivated and determined to make an important contribution to fundamental aspects of the physics of friction. The candidate must have followed a course in physics, mechanics or geophysics. A pronounced interest for experimental sciences is required as well as an openness to interdisciplinary projects.
The Physics Laboratory at ENS de Lyon is made up of 190 people, nearly half of whom are doctoral and postdoctoral students. The doctorant will be part of a research group focused mainly on friction and fracture problems with an experimental approach. The student is expected to get into the scientific community both in Physics and Geophysics, by attending national and international conferences and thematic schools.
The student will have to make national and international trips to attend conferences and schools, write scientific articles in English, make oral presentations in English and French.
Doctoral offer in physics of solid friction (F / M), for a period of three years and starting on October 1, 2021. The student is funded by the ANR project, DisRuptInt. Very strong motivation is expected, extensive training in physics, mechanics or geophysics and a strong taste for experimental sciences. Notions of image processing will be appreciated. Knowledge of English is required.
