Computer Analysis of Cylindrical Shells.

computer program, written for the IBM 7090 computer, is described which determines the internal forces, displacements, and reactions in a simply supported, multiple-cylindrical shell subjected to a set of known loads and boundary conditions. The structure analyzed may consist of up to 25 circular shell segments joined along their longitudinal edges. The program uses a direct stiffness solution in matrix form to analyze the multiple shell system and the formulation is based on the DonneiiJenkins shell equation. Results obtained using the computer program are presented and used to discuss the effect of a number of variables in the design of multiple cylindrical shells. [ABSTRACT FROM AUTHOR]
