In order to achieve the greatest possible contribution to increasing the resource and energy efficiency of technical systems with Lightweight Construction, good knowledge of Lightweight Materials is necessary. A material selection must be made for every Lightweight Design. All requirements regarding the functional property of the Lightweight Design, manufacturing, transportation, recycling and also costs have to be considered. In this course, an overview of possible Lightweight Materials will be developed.

A special focus will be put on fiber reinforced composites, as they have a particularly high lightweight potential and allow great design freedom. In order to exploit the potential of Lightweight Materials to the maximum, a good understanding of the mechanical behavior of the materials is necessary. This is particularly complex in the case of fiber-reinforced composites. Therefore, the description of the deformation and failure behavior of layered fiber reinforced composites is considered in detail. The exercises are partly carried out in the PC pool of the faculty in order to learn the implementation of complex calculations with Python.

The course is aimed at all students of the master's programs in mechanical engineering, industrial engineering, mechatronics and biomedical engineering who wish to acquire knowledge of the mechanics of Lightweight Materials.
