Classical Beam Theory

Buckling analysis of thin-walled composite channel beams is presented in this paper. The displacement field is based on classical beam theory. Both plane stress and plane strain state are used to achieve constitutive equations. The governing equations are derived from Lagrange’s equations. Ritz method is applied to obtain the critical buckling loads of thin-walled beams. Numerical results are compared to those in available literature and investigate the effects of fiber angle, length-to-height’s ratio, boundary condition on the critical buckling loads of thin-walled channel beams. Keywords: Ritz method; thin-walled composite beams; buckling.
