Course objectives:
|
By introducing of this subject the main goal to follow is to provide for graduate students of Mechanical Engineering Faculty, as well as for other students of technical faculties a subject, which focuses towards a selection of the new structural metallic and non-metallic materials. Actually, the aspect of materials selection are extended by chapters introducing new materials technologies, which are continuously introduced for manufacturing and processing of new advanced materials already in use.
