Elastic Analysis of a Circular Toroidal Shell Using Computer Modeling

摘要

The specific impetus for this work was a conceptual design of a submarine using the toroid as the pressure hull. This work is a continuation of the work started by Bowen (1987). As such, it is hoped that a better understanding of the behavior of a toroid under hydrostatic pressure can be realized. This work began with a review of efforts to solve complete toroidal structures. A specific toroid was then modeled in the BOSOR4 computer program to obtain displacements of the meridian under hydrostatic pressure. Functions were then derived that described the general form of these displacements. Using these functions as the assumed solution for the energy method an energy balance was made and a program was written to solve for the displacements of a generic toroid under hydrostatic loading.
