Keywords: finite element method, laminate plates and shells, continuous stress distribution, kinematic enhancement.

Summary

In this paper the strain field achieved from the basic Reissner-Mindlin kinematics with a quadratic displacement enhancement along the transverse direction will be improved to satisfy the continuity of the shear and normal stresses fields regarding transverse direction. This improvement is done keeping the total strain energy potential unchanged along a transverse line to the shell or plate. As a consequence, the good results achieved for the overall displacements and the normal stresses (parallel to the reference surface) are not missed. Moreover, no additional degrees of freedom are introduced and the resulting shear stress distribution is achieved from simple equilibrium considerations. Numerical examples are employed to demonstrate the potential of the proposed methodology and to compare the stress fields achieved for both calculations.
