In the present work, a finite element program based on the classical lamination theory improved by Vinson's weighting function to include transverse shear effects is developed for the analysis of laminated composite plates. The finite element analysis of a clamped three layered square symmetric laminate under uniform loading is carried out using 8-noded isoparametric elements having five degrees of freedom at each node. The effect of plate side-to-thickness ratio (a/h) 4, 10, 50 and 100 100 is studied on the maximum values of the non-dimensionalized central deflection (w), non-dimensionalized stress resultants [...] and non-dimensionalized stresses [...]. The variation of non-dimensionalized normal stresses [...] and shear stresses [...] through the thickness (z/h) of the laminate at plate side-to-thickness ratio (a/h) 10 is also studied.
