The equations of motion for the free vibration analysis of anisotropic thin-walled closed-section beams are derived using a variational asymptotic approach and Hamilton's principle. The analysis is applied to two laminated composite constructions. Th

A variationally and asymptotically consistent theory is developed in order to derive the governing equations of anisotropic thin-walled beams with closed sections. The theory is based on an asymptotic analysis of two-dimensional shell theory. Closed-

A shear deformation theory is developed to calculate the interlaminar stresses and energy release rate associated with mid-plane edge delamination growth in graphite/epoxy laminates. The analysis includes the effect of residual thermal and moisture s
