THE DESIGN OF STRAIGHT CLOSED MULTI-STRINGER PRISMATIC SHELLS UNDER FINITE DISPLACEMENTS

Abstract

A technique for designing straight closed prismatic shells accounting for the geometric nonlinearities and a set of force elements (stringers) is presented. Resolvents of the design equatons are obtained, which are represented in two different ways. It is shown that the geometrical nonlinearity in the above type of shells can be accounted for only using additional approximating functions of a special kind. A numerical method for analyzing the boundary problem for a system of ordinary differential equations with variable coefficients is chosen. The effect of accounting for the geometrical nonlinearity on the stressed-strained state of the shell of the above type is analyzed.
