BOUNDARY VALUE PROBLEM FOR BRANCHING TYPE FLEXIBLE COMPOUND STRUCTURES

Abstract

There is an efficient algorithm offered to calculate framing and compound coaxial shells of revolution, for each part of which accurate analytical solutions of corresponding differential equations of equilibrium are used. Conjunction of parts of branching type structure is per- formed automatically with the help of the graph theory mathematical tool. The unknowns of the resolving system of algebraic equations are the general solution arbitrary constants. Use of angular deflection method provides geometrical nonlinearity of the problem. The numerical example of calculation of the expansion bellows is presented.
