BUCKLING BEHAVIOR PREDICTION OF COMPOSITE LAMINATED STRUCTURAL ELEMENTS REINFORCED BY NANOSTRUCTURES USING THE FINITE ELEMENT METHOD

Using the Finite Element Method (FEM), in this study a buckling analysis of laminated plates out of composite material with inclusions of Multiwalled Carbon Nanotubes (MWCNT) in conducted. The nanocomposite matrix is calculated based on the rule of mixtures and the Halpin-Tsai model. The analysis is focused on the resulting effect on the material’s properties by the following parameters: random dispersion, agglomeration of the Multiwalled Carbon Nanontubes in the polymer matrix and waviness.
Afterwards, based on variations of the plate design (side-to-thickness ratio, boundary conditions, elastic modulus ratio, lay-up and the orientation of fibers) the critical buckling load is determined. Furthermore, by making use of the micromechanical Halpin-Tsai model, the critical buckling load is analyzed considering the use of nanotube fillers in a rectangular plate made of nanocomposite material.
Considering the theoretical and experimental data available in the open literature, the result of this study is in good agreement with the aforementioned data.
