| Abstract: | Coupled-admissible
functions are derived to obtain simple solutions for unsymmetrically laminated
beams. A kinematically admissible variation, as allowed by Rayleigh-Ritz energy
method, is assumed for the section rotation. Compatible admissible variations
for transverse and axial displacements are derived by making use of equilibrium
and boundary conditions. The proposed approach reduces the number of
independent unknowns by a factor of three compared to traditional Rayleigh-Ritz
method. Expressions for the axial and transverse displacements, section
rotation, fundamental frequency and buckling loads for simply-supported,
clamped-free and clamped-clamped beams are derived. |
