Detailed program and learning outcomes

Distinct Element modelling of granular materials, rocks and stone structures

The course is devoted to present the fundamentals of the Distinct Element Method (DEM) and to show its application to granular materials and blocky systems, such as rock masses and stone structures.

During the course students will learn what problems are best suited for a DEM approach compared to other numerical or analytical methods.

Students will be given rules for a reliable model set-up and the choice of the appropriate parameters. Modelling strategy and the procedure of the simulations will also be thoroughly discussed through practical examples that will guide the students in solving rock mechanics and structural problems.
