Skripchenko N. Contact interaction of complex-shaped details of engineering structures with local compliance of the surface layer

The object of study - the stress-strain state of complex-shaped smooth and rough bodies during their contact interaction. The purpose of research - development and implementation of methods for analysis of stress-strain state of complex-shaped rough bodies with their contact interaction. The methods of study: the boundary element method, the finite element method, the methods of variational inequalities, the boundary integral equations method, the method of collocation, the method of contact sheets. Theoretical and practical results: developed integrated physical and mathematical models and methods for describing the stress-strain state of contact rough bodies. Created f software-and-model complex for analysis of contact interaction of complex-shaped rough bodies. The novelty: developed mathematical models that take into account the different distribution of the gap and the rough layer compliance; developed methods for solving problems of the analysis of the stress-strain state complex-shaped rough bodies in accordance with their contact interaction. The degree of embedding: results of the thesis are introduced at PJSC "Azovmash" (Mariupol) and PJSC "Karlovski Engineering plant" (Karlivka, Poltava region.), National technical University "Kharkiv Polytechnic Institute" (Kharkiv). Scope of application: mechanical engineering, engineering of the armoured tanks, bearing industry.
