NONLINEAR ANALYSIS FOR AXISYMMETRIC ELASTIC STRESSES IN RING-STIFFENED, SEGMENTED SHELLS OF REVOLUTION

Abstract

The finite-difference method is used for the nonlinear analysis of shells of revolution consisting of elastic shell segments of various geometries and wall constructions joined by elastic rings. The analysis and associated digital computer program were developed in response to the need for a better design tool for practical shell structures. Numerical results are presented for displacement and stress distributions in various pressure vessels. Particular emphasis is given to systems in which nonlinear effects are important and may influence the design. Values calculated with linear theory are compared with those from nonlinear theory.
