Research methods include methods of analytical mechanics, applied theory of vibrations and impact theory, a method of object-oriented programming and visual design software for development of special computer algebra system (SCAS) and software, creep theory and long-term strength methods, continual damage theory. The project goals - scientific and technical problems solution that include theoretical and applied developments by taking into account methods developments for numerical and analytical analysis of durability for deformable bodies under unsteady creep and dynamic processes in discrete mechanical multi-body systems by using analytical computing in SCAS. The main project objectives include: theoretical developments concerning the further methods development for numerical-analytical analysis of durability of deformable bodies during creep process with new method developing for creep solutions of space bodies by using of the Bubnov-Galerkin method with global approximations and structural method of R-functions theory; development of analytical tools for computing in SCAS to solve a problems of analysis and synthesis of industrial machines, robots, manipulators and multi-body systems. Project results: new methods development of numerical-analytical analysis of durability of deformable bodies under creep and non-dynamic processes in discrete mechanical multi-body systems, which are suitable for using in relevant calculations of constructional elements of modern technical systems. The theoretical results can be used to develop new analytical computer methods for calculating the dynamics of machines and technical systems and software - in the practice of machine building planning-design offices and in research-development offices for analysis and synthesis of modern and new technology on the design stage, refinement, production and operation.
