After the course, the student is able to:
- Describe / give an overview of research possibilities in the field of multiscale materials;
- Face Multi Scale Mechanics problems with a research approach;
- Name and revise arguments from mechanics from solids and fluids from a micromechanical point of view;
- Relate micromechanical approach and classical continuum mechanics to fully describe the behaviour of materials with internal structure;
- Analyse material behaviour at particle level using the Discrete Element Method simulations and compare this to theoretical models;
- Perform small scale experiments on discrete materials.

The course covers individual learning assignments and activities within the fields of specialization in the group MSM. The different objectives described in the previous section are reached in the following way.
1. Describe / give an overview of research possibilities in the field of multiscale materials/
2. Face Multi Scale Mechanics problems with a research approach.
Each component of the group will illustrate its research topic or give lectures in its specific field/background. The course is articulated in different modules, coordinated by the chair of the group (S. Luding) and the four assistant/associate/adjunct professors (I. Ostanin, V. Magnanimo, W. den Otter, and A. Thornton). The multidisciplinary approach to the problem, due to the different backgrounds of the researchers (applied mathematicians, physicists, engineers), is an added value of the course in the perspective of providing a wide range of research approaches to the students.
3. Name and revise arguments from mechanics from solids and fluids from a micromechanical point of view/
4. Relate micromechanical approach and classical continuum mechanics to fully describe the behaviour of materials with internal structure.
Topics in these moduli of the course are:
Contacts models
Sound Propagation in discrete media
Instability analysis
Micro-Macro Transition Methods
Micro-Macro Transition Practice
5. Analyse material behaviour at particle level using the Discrete Element Method simulations and compare this to theoretical models.
Topics in this modulus of the course are:
Contact Detection in MD
Particle Methods and MD for fluids
Implementation in DEM of the topics in the previous session
6. Perform small scale experiments on discrete materials.
Small scale experiments on glass beads, sands and powders will be performed in the lab related to the numerical and theoretical analysis.
The course is not strictly scheduled in the time table of the program, since it will be adapted to the students request and, for each of them, an individual “first-research line” will be followed. The content is case specific. The answers to the research question may be found by literature study, by simple experiments, by (numerical) analysis and modeling, by theoretical analysis, or via a combination of these.
