The buckling study of laminated composite thin plate is performed at two different levels i.e. analysis of lamina to compute its properties and buckling analysis of laminated composite thin plate with various parametric values. In analysis of lamina, relations from previous literature results have been used to determine elastic properties of boron-epoxy, glass-epoxy and jute-epoxy lamina. In analysis of lamina, previous literature relations were incorporated with MATLAB to determine properties of lamina for different values of fiber volume fractions. The buckling analysis have been done with laminated composite thin plate under uniaxial compressive loading. The computational results have been validated with analytical results. We have observed, maximum error in computational and analytical methods is 6.03%. In present buckling study, buckling load of laminated composite thin plate has been computed for various parameters i.e. such as fiber volume fraction (V), ply orientation angle (θ), aspect ratio, thickness ratio, boundary loading conditions and geometry of cut-out with different composite materials. From the results, it has been found that buckling load increases linearly with fiber volume fraction whereas minimum buckling load is observed for ply orientation angle from 15 to 30 degree. The buckling load increases with increase in aspect ratio whereas it decreases with increase in thickness ratio. The buckling analysis has also been done with different boundary conditions and cut-out geometry which are required for various applications.ennullThesis
