Buckling of arbitrary quadrilateral anisotropic plates

Thermal buckling analysis of skew fibre-reinforced composite and sandwich plates using shear deformable finite element models

“…Reddy and Palaninathan [1] have employed a triangular ®nite element based on classical laminated plate theory. Jaunky et al [2] and Wang [3] have used the Rayleigh±Ritz method incorporating ®rst-order shear deformation eects. Very recently, Babu and Kant [4] have presented two C 0 shear deformable ®nite element formulations for the buckling analysis of skew laminated composite and sandwich panels.…”

Static, Vibration and Buckling Analysis of Skew Composite and Sandwich Plates Under Thermo Mechanical Loading

“…Laminated composite structures are weak in shear due to their low shear modulus compared to extensional rigidity. Considerable research (Reddy and Palaninathan, 1995;Jaunky et al 1995;Wang, 1997;Babu and Kant, 1999) has been published on buckling response of skew composite laminates. In these investigations, numerical methods such as the finite element method, the Rayleigh-Ritz method, etc.…”

“…Reddy and Palaninathan (1995) used an triangular finite element based on the classical laminated plate theory. Jaunky et al (1995) and Wang (1997) employed the Rayleigh-Ritz method incorporating first-order shear deformation effects. Babu and Kant (1999) presented two C 0 shear deformable finite element formulations for the buckling analysis of skew laminated composite and sandwich panels.…”
