Course Aim
The aim of the course is for the student to:

- have acquired the basics of the space environment's challenges in terms of material technology.
- have acquired basic knowledge for the construction and behavior of high-performance materials used in the aerospace industry.
- have acquired basic knowledge of how to estimate properties of composites, ceramics and alloys.
- know the most important degradation mechanisms that arise in the results of thermal and mechanical loads and lead to fatigue and lifetime reduction of materials.
- know typical solutions to structural problems in space and estimate effects of  the space environments on the spacecraft structur.
- be able to carry out numerical simulations using commercial codes to analyze and optimize structures.
- be able to use simple structural models of thin flat and shell-shaped linear elastic bodies,
- be able to calculate voltages and deformations in such structural models,
- be able to carry out and evaluate practical experiments with such structural models,
- be able to methodically attack and solve strength-technical problems for the current class of structural models.
