Modeling of the stress-strain state of the flexible multilayer membranes

Paper, the mathematical model of deformation of laminated shells under simple and complex loading, allowing uniformly present on the basis of the deformation theory A. A. Ilyushin stress-strain state. The model takes into account the real appearance of the chart and allows you to explore the deformation of a flexible heterogeneous membranes of variable rigidity, longitudinal and combined loading. Developed methods for solving large systems of nonlinear equations based on the General procedure iteration algorithms were constructed using combinations of different methods.
