“…The flattening phenomena of curved tubes were investigated theoretically by Clark and Reissner [11] by using various energy principles and approximate methods. In recent years, the flattening of long cylindrical tubes has also been investigated, among others, by Stephens et al [26], Almroth and Starnes [3], and Knight et al [17], where the finite element method was employed. Analytical approaches for the Brazier effect on long tubes are also presented by Calladine [9] and Gantes and Gerogianni [16].…”

This paper presents a semi-analytical finite element analysis of pole-type structures with circular hollow cross-section. Based on the principle of stationary potential energy and Novozhilov's derivation of nonlinear strains, the formulations for the geometric nonlinear analysis of general shells are derived. The nonlinear shell-type analysis is then manipulated and simplified gradually into a beam-type analysis with special emphasis given on the relationships of shell-type to beam-type and nonlinear to linear analyses. Based on the theory of general shells and the finite element method, the approach presented herein is employed to analyze the ovalization of the cross-section, large displacements, the P-effect as well as the overall buckling of pole-type structures. Illustrative examples are presented to demonstrate the applicability and the efficiency of the present technique to the large deformation of fiber-reinforced polymer composite poles accompanied with comparisons employing commercial finite element codes.
