Algorithm for calculating flat-loaded shells of environmental structures

Abstract Structures made of thin-walled shells are widely distributed elements in the environmental protection systems. In this connection, it is necessary to develop their effective and refined calculation. The point shell structures considered with a plane load initial position, deformed after j loading steps (displacement vector) adjacent (j + 1) step. displacement increments derivatives taken as nodal unknowns. vectors inner finite element represented basis, components approximated through unknowns using Hermite polynomials 3rd degree. To determine state shell, algorithm method discrete continuation respect parameter vicinity singular used, which increment at step desired parameter. Based on obtained dependencies, step-by-step calculation procedure organized, allows you get correct results if there special point.
