FINITE ELEMENTS FOR BEAM CROSS-SECTIONS OF MODERATE WALL THICKNESS

The torsion and shear load problems of elastic beam cross-sections of moderate wall thickness are formulated in terms of finite elements with the warping function as primary variable. By introduction of suitable internal degrees of freedom in the shear problem the stiffness matrices of both problems become identical. The method makes no distinction between open and closed cross-sections. An efficient pc implementation is discussed and illustrated by examples. (Author/TRRL)
