21st GAMM Seminar on Microstructures
TU Wien, January 28, 2022
The GAMM Seminar on Microstructures is the annual meeting of the GAMM activity group on Analysis of Microstructures. This year's workshop is organized in cooperation with SPP 2256 "Variational Methods for Predicting Complex Phenomena in Engineering Structures and Materials" funded by the German Science Foundation. The workshop will focus on various aspects of microstructures in solid mechanics, material science, and applied mathematics:
- Modeling materials with microstructure (plasticity, damage, phase transitions, electro-magneto-mechanics, ...)
- Experimental results on the formation and evolution of microstructure (lamination, phase transformation, ...)
- Mathematical analysis, variational formulations, non-convex problems, relaxation methods
- Multiscale methods and computational tools for the determination of effective properties of microheterogeneous materials
The workshop gives the opportunity to discuss and to compare different approaches to the above fields. It provides a platform for the interaction among young and established researchers in solid mechanics, mathematics, and material science.
