A hybrid-stress finite element for nonuniform filament-wound composite box-beams

A two-node, hybrid-stress finite element is formulated for static and dynamic analyses of linearly tapered, filament-wound composite box-beams. The effects of shear deformation and rotatory inertia are taken into account. The extensional, flexural and torsional actions are modeled. The element is assessed by a number of static and dynamic test problems for uniform and nonuniform, isotopic and composite box-beams. The results show the accuracy of the formulation.
