Purpose of research is creation of methods, models and tools for analysis of stress-strain state and geometric synthesis of complex shaped bodies by enhancement of mathematical models of micro and macro mechanics of contact interaction It allows to solve problems of project improving of technical level of domestic industry production on global level. Research methods are: finite and boundary elements methods, complemented and developed to take account of local contact stiffness of interacting bodies; Hertz method; method of variational inequalities; Lagrange multipliers method and Calker variational principle for justification of variational formulations of contact problem; method for geometric synthesis of contacting surfaces by analyzing the contact interaction; method of parametric describing of complex objects for their variation modeling. Results of work are: ways, tools and methods of computer modeling and calculation of stress-strain state of complex shaped bodies taking into account contact interaction for providing the durability of constructions. The results are recommended to use for stress-strain analysis and the synthesis of geometric form of elements of engineering constructions with high performance characteristics taking into account contact interaction.
