Buckling of multilayered composite plates by natural shear deformation matrix theory (Q1912050)

The study discusses buckling of multilayered composite plates from the standpoint of a natural shear deformation theory which is developed and shaped by means of matrix language on a model facet three-node triangular finite element. Isotropic, sandwich, and hybrid plates can also be treated. It is shown that by invoking a physical decomposition and lumping concept, evolved through the adoption of a natural coordinate system in harmony with the given element geometry, an assembly of three edge-beams is created and is solely responsible for the carrying of the transverse shear forces.
