Abstract

A finite element investigation of cantilevered swept wings under transverse load is performed using a conventional idealization by a high-precision triangular plate bending element and by a mixed idealization using high-precision triangular elements near the fixed end and torsion-flexure coupled beam elements over the out-board portion of the wing and inter-phase plate beam element in the transition region. The latter considerably reduces the problem size13; and solution time required. Extensive results for a wide range of geometrical parameters are presented, and these would serve as useful design charts.
