Essay

The object of the research is nonstationary deforming the elements of the structures such as systems of beams and shells. The research aim is to develop efficient methods of inverse problems solutions for the systems of beams and shells which are being deformed jointly. The methods are analytical-numerical methods of mathematical physics, methods of mathematical analysis and functional analysis in mechanics of the deformable solid, which are based on discretization of continuums under consideration. The new methods for solution of ill-posed inverse problems of loads identification which act on elastic systems of beams and cylindrical shells have been developed. The results can be used to receive information about the strength and character of non-stationary loading which acts on the systems in the form of beams and cylindrical shells. The methods for joint solution of direct and inverse problems of finite length beam pulse loading have been improved. The results of the research have been introduced at PC "Promtest". The field of application: machinery building, oil and gas processing industry.
