Objectives of the discipline

Formation of social knowledge on the composition, mechanical properties, production technology and applications of modern materials of different classes as well as the calculation of machine parts, structural elements of modern materials working under conditions of varying loads, friction and combined effects.

The student must be able to:

– apply the gained knowledge for a reasoned choice of modern structural materials, as well as the calculation of machine parts as well as structural elements from modern materials, operating under conditions of varying loads, friction and combined effects.
