Immaterial movements : theoretical and numerical points of view
Info
As part of the events linked to the award of the insignia of Doctor Honoris Causa of the University of Liege to Mr. Nicolas MOËS, Professor at the Ecole Centrale de Nantes and Member of the French Academy of Sciences.
The Faculty of Applied Science - School of Engineering and
the Aerospace and Mechanical Engineering Department
has the honor to invite you to the seminar entitled
IMMATERIAL MOVEMENTS:
THEORETICAL AND NUMERICAL POINTS OF VIEW
Friday, the 18th of March 2022 from 11h to 12h30
The presentation is organized in three parts.
In the first part, we will recall the importance of immaterial surfaces in mechanics, physics and science in general. These surfaces are the seat of discontinuities and migrate through matter (unlike material surfaces which are attached to matter).
In the second part, we will study the common points and differences in the theoretical modelling of the motion of these surfaces according to the physics involved.
Finally, classical methods for tracking these surfaces will be presented as well as a completely new approach.
Short CV of Prof. Nicolas Moës
Nicolas Moës' research focuses on fracture and contact mechanics. The approach, called X-FEM, which he initiated in 1999 with Ted Belytschko and John Dolbow has greatly simplified the simulation of crack propagation by finite elements. More recently, with his collaborators in Nantes, he has created a theory unifying damage mechanics and fracture mechanics, as well as an original approach for the treatment of variational inequalities, such as those involved in contact.
