Learning outcomes:
After successfully completing this course, students will be familiar with the fundamentals of mechanical material behavior and its characteristic values and will be able to apply them to static and dynamic loads.
- They will be able to determine the characteristic values of a tensile test including those of the plastic behavior, interpret them and apply them to simple automotive components.
- They will be able to trace the properties of a material back to its microstructure and thus, influence the properties by changing the structure.
- They will be familiar with the microstructures in the iron-carbon phase diagram and will be able to select appropriate annealing and hardening processes with the aid of time temperature transformation diagrams.
- They will be able to select suitable surface treatment processes with regard to the materials being used.
- They will be able to select suitable materials for various automotive applications.
Within the framework of a final interdisciplinary project (FT04.2, FT04.3, FT04.4 and FT04.5), the students must design a small component in a team after determining loads, then dimension it in accordance with the loads and stresses and produce a production drawing in accordance with the standards. In this way, students will become familiar with the interaction of sub-disciplines and important interfaces and be able to practice running through the sequence of development steps, which they can then, in subsequent projects, independently transfer to other components.
