The aim is that the issue of mechanical impact (collision) procedures as wide, and point out the methods of describing processes occurring in the solid body in a short time period of collision, including aspects from the standpoint of classical mechanics, the contact stresses and strains, wave propagation phenomena and occurrence of plastic deformations.

Knowledge of four major aspects in the evolution of impact theory: • Classical mechanics • Contact mechanics • Plastic deformation • Stress wave propagation. An ability to identify, formulate, and solve simple problems in impact mechanics. An ability to systematically review, analyze, assimilate and interpret professional literature and innovations in spectrum of different theories for collision. An ability to produce high quality research, and disseminate effectively the research output in reputable international journals, conferences, research proposals and other scientific venues.
