The basic module "Strength of Materials and Materials Science" examines the two closely related topics of strength of materials and materials science and provides students with a basic knowledge of the mechanics of materials and material properties. The module is an essential building block for understanding the loads on mechatronic systems. Students are enabled to select materials specifically and to assess their application in mechatronic systems.

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Written examination or
• Written electronical examination

Materials engineering: fundamentals of physics and chemistry

Mathematics: trigonometry, algebra, basics of differential and integral calculus, simple differential equations

Students who have successfully completed this module,
- can name the terms mechanical stress and distortion and explain the differences.

- can name and explain the material laws and material properties required for strength theory.
- can name different strength hypotheses and explain their application.
- can name and explain the basic types of load (tension, compression and temperature change in bars, bending, shear and torsion).
- describe the significance of strength theory within engineering using practical examples

Students can estimate and analyse the strength hypotheses for specific materials.

Students can transfer the strength hypotheses to specific application examples and evaluate them for different material classes.
