| Summary |
|---|
| The course deals with the deepening study of basic mechanical properties of special mechanical properties. The practical examples presented here the reasons which led to the introduction of specific test methods related to fatigue, corrosion fatigue, stress corrosion cracking, fracture behaviour of steels and creep resistance of steels to environments containing hydrogen sulfide. In addition, special methods are presented in the field of non-destructive testing for the detection of internal defects in the material volume. |
| Learning Outcomes of the Course Unit |
|---|
1) Student will be able to define special material characteristics of the
main degradation processes.
2) Student will be able to describe the determination of special material
characteristics according to relevant standards DIN EN respectively CSN EN
ISO.
3) Student will be able to describe a new method of testing material
properties.
4) Students will be able to decide in which cases it is necessary to
determine special mechanical characteristics of the material. |
