Abstract
A doubly curved element for a shell of revolution which has arbitrarily
curved meridians is developed and analyzed. Meridional curvature is
calculated using a highly accurate polynomial approximation. The displacement
functions selected satisfy interelement compatibility and
contain all the lower modes of a complete set of straining functions.
Non-straining modes corresponding to rigid body motions are introduced
into the final stiffness matrix for any conceivable rigid body motions.
The direct stiffness method was used to construct a stress and
strain analysis program and the results of the analysis of a few problems
are compared to classical solutions to establish the integrity of the
element.
