F. Vankeulen et J. Booij, REFINED CONSISTENT FORMULATION OF A CURVED TRIANGULAR FINITE ROTATIONSHELL ELEMENT, International journal for numerical methods in engineering, 39(16), 1996, pp. 2803-2820
The present paper considers a finite rotation formulation for curved s
hell elements with rotations about the element sides as nodal degrees
of freedom. Attention is mainly on the derivation of a consistent fini
te rotation formulation. Significant simplifications of the governing
equations are presented. These simplifications lead to more efficient
finite element implementations. Numerical examples demonstrate the dif
ferences between the present consistent and previous approximate formu
lations.
