Subject aims expressed by acquired skills and competences

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.

Teaching methods

Experimental work in labs


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.
