In this paper the
influence of different boundary conditions on geometrically nonlinear response
of laminated composite plates is analyzed. Mathematical model, based on
layer-wise displacement field of Reddy [1], is formulated using the von Karman,
small strain large deflection theory. The principle if virtual displacements
(PVD) is used to obtain the weak form of the problem. The weak form is
discretized utilizing isoparametric finite element approximation. The
originally coded MATLAB program is used to investigate the influence of
different boundary conditions on geometrically nonlinear response of laminate
composite plates. The accuracy of the numerical model is verified by comparison
with the available results from the literature.
