We discuss a
theoretical formulation of shell model accounting for through-the-thickness
stretching, which allows for large deformations and direct use of 3d
constitutive equations. Three different possibilities for implementing this
model within the framework of the finite element method are examined: one
leading to 7 nodal parameters and the ramaining two to 6 nodal parameters. The
7-parameter shell model with no simplification of kinematic terms is compared to
the 7-parameter shell model which exploits usual simplifications of the
Green-Lagrange strains. Two different ways of implementing the incompatible mode
method for reducing the number of parameters to 6 are presented. One
implementation uses an additive decomposition of the strains and the other an
additive decomposition of the deformation gradient. Several numerical examples
are given to illustrate performance of the shell elements developed herein
