Sklepus O. Methods and software development to solve problems of creep plates with complex form on the base of R-function theory

Object of investigation are plates with the complex form under different conditions of fixing and loading. The purpose of the work is the development of the new effective method of the creep problem solving of the plates with the complex form based on joint application of R-functions theory, variational Ritz's method and Runge-Kutta-Merson method. The methods of investigation are the methods of R-function theory, variational Ritz's method and Runge-Kutta-Merson method. Theoretical and practical value consists in the development of methods, algorithms and software on C++ language for plate creep and life time investigation. Novelty: the new method of the creep problem solving of the plates with the complex form is developed; The constructive means of R-functions theory as constructed solution structures, which precisely satisfy to the boundary conditions of creep plate problem, were developed. Application in branches where thin-walled elements are used i.e. in aerocosmic, building, metallurgical and other branches is planned.
