Subject aims expressed by acquired skills and competences

The student will be able to define the special material characteristics of the main degradation processes and determine special material characteristics according to the relevant standards ČSN EN, resp. ČSN EN ISO. The student also learns to characterize new methods of material properties testing and to assess in which cases it is necessary to determine the special characteristics of the material.

Summary

The course deals with deepening the study of basic mechanical properties with special mechanical characteristics. Practical examples illustrate the reasons for introducing special test methods for fatigue, corrosion fatigue, corrosion cracking, steel fracture behavior, creep and resistance of steels in hydrogen-containing environments. Special methods are also presented in the field of non-destructive testing for the detection of internal defects in the material volume.
