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