Refined Mixed Method Finite Elements for Shells of Revolution

Title
Refined Mixed Method Finite Elements for Shells of Revolution
Description
A rotational shell finite element with mixed stress and displacement variables is derived for the case of arbitrary static loading. Accurate representation of the shell geometry together with high-order approximations for the dependent variables are combined to formulate a comparatively precise element containing only the basic number of degrees of freedom. Representative examples are used to study the convergence of the element and to provide a basis of comparison with a similar displacement-type element.
