Large amplitude vibration analysis of laminated composite beam with axially immovable ends is investigated with symmetric and asymmetric layup orientations by using the Rayleigh–Ritz (R–R) method. The displacement fields used in the analytical formulation are coupled by using the homogeneous governing static axial equilibrium equation of the beam. Geometric nonlinearity of von-Karman type is considered...
The present study proposes simple, elegant, and accurate closed-form expressions for predicting the post-buckling behavior of composite beams with axially immovable ends using the Rayleigh–Ritz (R–R) method, where geometric nonlinearity arises from mid-plane stretching of the beam. The displacement fields used for the analysis are coupled using the axial equilibrium equation of the composite beam...
