Department scientific directions

• At the Department and its research laboratory there are different studies on research and development of new materials with high damping properties of basic processing technology, and studies of internal friction in these materials. In the research laboratory original methods of studying structure and properties of materials were developed, e.g., internal friction in the study samples of materials with different energy dissipation mechanism with complex loading scheme. A number of developed steels and alloys were tested and introduced in the aviation, engineering and shipbuilding.
