Subject aims expressed by acquired skills and competences

The course objective is to familiarize students with problems of production and operation degradations in engineering materials. The course will provide students with the basic information on production and operation degradation in engineering materials. Students will learn to regard material as a chemically and structurally heterogeneous body, whose states can be greatly affected by exploitation conditions. Students should be able to assess the effect of the technologies used as well as of the conditions of exploitation on the properties of the materials of component parts and structures.

Summary

The course is aimed at basic knowledge of damage processes in materials. Lectures are devoted to brittle and ductile fracture, fatigue, creep, corrosion damage and wear of surface materials. Knowledge of the basic mechanisms of degradation processes is exercised in solving technical.
