GAMM Rundbrief 2002/Heft 2

Wissenschaftliche Tagungen 61
The course is addressed to PhD Students, post-doctoral researchers and research
engineers interested in broadening their knowledge in the interdisciplinary field of
materials science and continuum mechanics. Especially the problems related with changing
microstructures are of high theoretical and practical relevance.
Invited Lectures:
M. Berweiller - LPMM - ENSAM, Metz, France 6 lectures on: Micromechanics of
displacive (martensitic) transformation in heterogeneous and non-linear solids.
Martensitic transformation in SMA’s and TRIP steels. Experimental results for SMA
and TRIP materials. Modelling the Superelastic Behaviour of SMA’s and composites.
Micromechanics of the TRIP phenomenon: transformation induced plasticity, strain
induced transformation, thermomechanical couplings.
F.D. Fischer - Montanuniversität, Leoben, Austria 6 lectures on: Transformation- and
twinning condition for a microregion (TTC). Energy balance and dissipation conditions
for a microregion, interaction with the local stress state. Chemical energy in the case of
displacive, massive and diffusive transformations. Implementation of the TTC in a
finite element model. Applications.
P. Fratzl - E. Schmid Institute of Materials Sciences, Leoben, Austria 6 lectures on:
Modelling the microstructure evolution during phase transformation and phase
separation by phase field models and atomistic simulations. Dynamic and extended
Ising model, Phase field model, Cahn Hilliard equation. Stability, spinodal
decomposition. Kinetics of homogeneous precipitation and interface motion. Effects of
misfit strains and anisotropy. Influence of vacancy-solute interactions, simulation of
precipitate rafting. Extensions of the phase field model: diffusion less transformations,
dislocations and phase separation, dislocation movement.
R. Kienzler - University of Bremen, Germany 6 lectures on: Configurational Mechanics
of Materials. Eshelbian and Newtonian forces. Change of the configuration related with
the location of a dislocation, size or shape of a cavity, inclusion, crack, phase boundary
etc. Application to defects and fracture mechanics.
F. Montheillet - ENSMSE Saint Etienne, France 6 lectures on: Various recrystallization
mechanisms in metals, sub-grain and grain boundary migration and dynamics.
Continuous and discontinuous dynamic recrystallization. Nucleation of new grains,
generation of low angle sub grain boundaries. Influence of material purity, strain rate,
temperature on the possible transition between the mechanisms. Mechanisms for grain
growth. Modelling of recrystallization.
J. Svoboda - Institute of Physics of Materials, Brno, Czech Republic 6 lectures on:
Phenomenological description of processes based on non-equilibrium linear
thermodynamics and extremal principle. Diffusion and vacancies in multicomponent
systems. Modelling of diffusive phase transformations. Solute segregation and drag in
migrating interfaces. Evolution of precipitate structures.
