Abstract
The structures formed by laminated composites have great application in civil engineering. Mainly covering of industries with trapezoidal tile with acoustic insulation. Another application of the composite system is in the green layers of the roof. So this paper discussed a formulation for stability analysis of laminated plates through the Finite Element Method. The formulation presented allows the use of triangular and quadrilateral elements with different interpolation orders. In the numerical examples, the quadratic finite element with quadratic interpolation C3D8R was used to study its behavior. The reduced integration technique was used to alleviate the shear block problem. The behavior of these elements was evaluated by comparing the results obtained by FEM with analytical solutions based on the classical laminated plate theory. The results show that the elements provided excellent precision results for cross-layer laminates and single and biaxial angles and loads.
