The specific impetus for this work was a conceptual |
|
design of a submarine using the toroid as the pressure |
|
hull. The designers could not find a ready body of |
|
knowledge to obtain scantlings for their pressure hull. |
|
This work began with a review of efforts to solve |
|
complete toroidal structures. Several works were found |
|
which addressed general shells and extended into partial |
|
toroids, but the solution of a complete toroid was not |
|
found to be a common exercise. Some of the these works |
|
are briefly reviewed. An attempt was then made to solve |
|
for the displacements in a thin walled circular toroid |
|
using the energy method. Several problems were identified |
|
associated with the structure geometry which make the |
|
solution for the complete toroid difficult. In addition, |
|
the functional used for the energy method needs to be |
|
more complex than the simple trigonometric or power |
|
series functionals used in this work. These two areas, |
|
geometry and functionals, are fertile areas for further |
|
study. |
