Abstract

A tapered beam element with torsional flexibility and transverse shear deformation is developed for use in swept plate studies. Recently established guidelines for selective reduced integration allow the use of independent interpolation functions for the transverse deflection, rotation and torsional rotation, to obtain an element that does not lock in the extremely thin situations encountered in thin beam/plate analysis. The element is tested for free vibration, and for the static case of a severely swept cantilever plate of high aspect ratio subjected to a uniform distributed load. The results indicate very good performance of the element.
