Abstract

A sound variational framework applicable to shallow shell analysis is proposed in this work. The addition of the so-called drilling degrees of freedom, usually absent in the shell analysis, is facilitated within the proposed framework at the continuum level. Therefore, it provides a solid theoretical basis for the development of thick and thin curved shell elements with six degrees of freedom per node.
