Finite element
formulation for refined linear analysis of multilayered composite shells is
presented. An element has seven dof/node: three displacements of the middle
surface, two rotations of the shell director and two displacements associated
with the wrinkling of the cross-section. An underlying model is obtained by an
extension of the first-order shear-deformation theory. We adopt an assumption of
zig-zag variation of displacements trough the thickness of the laminate, and we
use Reissner's mixed variational principle which allows independent through the
thickness interpolation of two transverse shear stresses. Those stresses satisfy
interlaminar equilibrium conditions. No shear correction factors are used.
Performance of the derived finite element is illustrated with numerical example
