parallel methods, optimization and inverse modelling, software and tools.
Applications of multigrid, paticulary in computational fluid dynamics, porous media
flow, computational mechanics, chemical engineering, biotechnology and statistical
physics.

Moving Discontinuities in Crystalline Solids
Advanced School: Coordinated by F.D. Fischer, Montanuniversität, Leoben, Austria M.
Berveiller, LPMM - ENSAM, Metz, France
The thermomechanical behaviour of most of the crystalline solids is controlled by:
1.thermoelastic deformations of the crystal lattices,
2.inelastic deformations resulting from nucleation, motion and annihilation of lattice
discontinuities. Associated with these defects are discontinuities of the thermoelastic
behaviour and (or) inelastic strain discontinuities. The “static” part of the problem
(determining the stress fields related to these defects) is well known since the sixties.
More recently, a great interest was devoted to problems connected with the movement
of discontinuities, and with a more generalized definition of “forces”. Some of these
problems are listed below:
1. What is the thermodynamic (driving) force responsible for the evolution of the
interfaces whenever the chemical composition is changing or not?
2. How is this interface motion transmitted to the level of the Representative Volume
Element (RVE)?
3. How is the thermoelastic behaviour of the RVE affected by moving boundaries,
diffusion, plastic flow etc.?
4. Which are the effects of the coupling between different mechanisms: plasticity and
recrystallization, plasticity and phase transformation, diffusion and phase
transformation, plasticity and diffusion etc.?
5. Which algorithms are available to describe the change of the microstructure. The
aim of the course is to present research results of the last ten years as well as tools
for an algorithm formulation concerning the topics previously discussed.
