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.
