Department Material Concepts and Modeling (MM)

The Department of Material Concepts and Modeling was established in 2002 under the direction of Prof. Dr. Manfred Klüppel with the aim to answer the growing industrial requests concerning the field of physical modeling of elastomers.

The main research topic in this department is the elucidation of the relationship between the microscopic structure and the macroscopic properties of flowable as well as crosslinked, reinforced elastomer systems.

Special attention is paid to applied fundamental research of the physical properties of elastomers and the implementation of micro-structure based models.
