The results of research of a newly developed metal cylindrical panel in the course of its shaping, and procedure of verification of the computer model are presented in the paper. The computer model of the panel under consideration, developed through selection of the finite element as a result of reshaping designated to ensure the formation of a plastic hinge in the points of junction between the principal element (the plate) and the stripes, makes it possible to perform a sufficiently accurate analysis of experimental and theoretical data of structures of ribbed panels under consideration.
Application of the finite elements method in the course of development of computer models for the purpose of research of the process of shaping of ribbed panels at each stage of pumping of compressed air into the panel, makes it possible to assess the alteration of the stress-strained state of the structure and to identify the parameters of the new cylindrical ribbed panel with a high degree of accuracy, including such parameters as the radius of curvature , swell ratio , and compression ratio .

The Desargue configuration plays an essential role not only in projective geometry, being the main configuration in projective and perspective correspondence of rows of points and lines, but is also rich in applications in architectural and design engineering. The article describes the main aspects of planar and spatial configuration of Desargue, and fundamental principles having particular importance in the shaping theory based on projectography. The described configuration properties indicate the possibility of wide application in architectural design and engineering and allow predicting the effects of perception of rather complex architectural forms. Examples of a number of buildings are given, where in modern design solutions of architects spatial configuration motives are visible. Planar configuration option is often used as decoration and fencing. The authors conclude that researching the configuration of Desargue in different variants and modifications not only contributes to better understanding of the theory of perspective and shadows, but also provides opportunity to detect relations of the problems, which are different at the first sight. However it is necessary to take into account, that many postulates of the theory are quite complicated and significant amount of time is needed for learning it.
