| Abstract | In this study, a six-node degenerate finite element for geometrically nonlinear analysis
of thin-walled structures is developed by using assumed strain method for the a:ansverse shear
term and the reduced integration technique for the inplane shear term. The class of combined
flexural and torsional problems is considered. The element is degenerated from the three
dimensional field equations, using certain assumptions justified for thin-walled sections, so
that effects of warping restrained conditions can be fully accommodated. The nonlinear analysis
is referred to the total Lagrangian configuration. The nonlinear equilibrium equation is solved
by using the linearization by the Newton-Rapson iteration process.Various numerical examples
are presented to demonstrate the versatility and the effectiveness of the element. |
