Title

Finite Element Analysis of Thin-Walled Structures Based on the Modern Engineering Theory of Beams

Description

A practical method of overall finite element analysis of thin-walled beam-type structures such as aircrafts, ships, bridges etc. is proposed in this paper.

The analysis consists of two steps, the first of which is evaluation of various sectional properties of a beam with arbitrary cross section, especially St. Venant's torsional stiffness and warping torsional stiffness. The second step is solution as well as formulation of overall stiffness equation of a given structure by using general stiffness matrix of a beam element which is defined with respect to an arbitrary point on the cross section. For justification of the proposed method, results of shear flow analysis of some beam cross sections and overall torsional analysis of a container model ship as well as an actual container ship with their experimental data are shown.
