ITERATIVE METHODS OF RESEARCH OF THE THIN-WALLED ELEMENTS OF CONSTRUCTION

The mathematical model of elastoplastic deformation of flexible covers by the difficult loading allowing the investigating the intense deformed state on the basis of the deformation theory of A. A. Ilyushin, is developed in this article. The model considers the compressibility of material, the real type of the diagram, allows to investigate deformation of flexible non-uniform covers of variable rigidity be the cross, longitudinal and combined loading. The new effective method of calculus mathematics is entered: double-link method. The methods of the decision of big systems of the nonlinear equations based on the procedure of the general iteration are developed; the algorithms using combinations of various methods are constructed.
