Application of methods of the theory of perturbations in flat problem of equally-stressed reinforcing of metal-composite plates at steady creep

The problem of equally-stressed reinforcings of the plates loaded in their plane and working in condition of steady creep is solved by methods of the theory of perturbations. The possibility of existence of several alternative solutions of the problem under consideration is demonstrated which can be selected reliably, using the algorithm developed. Explicit projects of equally-stressed reinforcings of a doubly-connected plate are constructed at different types of its load.
