The paper deals with the 3-D stress analysis of laminated composite plates using a layerwise
displacement model of Reddy, that assumes piece-wise linear variation of all displacement
components and the quadratic variation of interlaminar stresses within each layer of the plate.
Based on the assumed displacement field, kinematic relations, 3-D constitutive equations of both
lamina and laminate and governing equations of motion have been derived. Starting from the
strong formulation of the full layerwise theory (FLWT), family of layered finite elements has
been developed and implemented in original object-oriented MATLAB code. GiD software is
used for the pre- and post-processing.
The parametric effects of plate side-to-thickness ratio, mesh refinement in- and out-of-plane
and applied element type on total deflection and stress distribution in the considered laminate are
shown. The accuracy of the present model is verified against the existing data from the literature
and the ...commercial software. The possibilities for the further improvement and applications of
the model are briefly presented.
