ESR2 - Multi-physics reduction approach for nonlinear complex interfaces

Recruiting Institution/Company: Ecole Centrale de Lyon (France)

PhD awarded by: Ecole Centrale de Lyon (France)

Objectives: This project aims to develop a multi-physics approach to model interfaces under complex dynamic loadings, with the objective of integrating phenomena like wear, friction and heat exchange between volumes in contact and implement them in numerical solvers. The purpose of this research is to carry out accurate modeling and computation of friction interfaces subject to dynamic loadings. Specific nonlinear reduction techniques will be developed to make possible such complex computations.

Expected Results: The new developed algorithms will allow to :
- simulate realistic physical phenomenon at interfaces and evaluate the most significant parameters in such modeling (friction, wear, thermal, ...)
- define an efficient non-linear model reduction strategy adapted to complex interface behavior

Planned secondment(s):
SNECMA: insights on existing experimental and numerical data
SAFRAN: inputs for developing and implementing a complex algorithm
SNECMA: validation and/or consolidation of the developed algorithm using SNECMA in-house solver

Profile of the ideal candidate:

•             A strong background in “mechanical vibrations” and “mathematics”
•             Interest in theoretical developments and numerical applications
•             Some knowledge in the field of tribology and numerical techniques will be appreciated
