Abstract
A comparison of numerical schemes for the nonlinear behavior of inflated membrane boom structures due to the wrinkling is investigated. For a finite element analysis, two different numerical schemes are applied . In t he first scheme, the structure is numerically modeled using membrane elements , and taut, wrinkled and slack membrane states are determined at each load step using the Tension Field theory . In t he second scheme, the structure is modeled with shell elements , and the nonlinear deformation is analyzed using a post -buckling analysis . A comparative study of the wrinkling problems of the inflated membrane boom in bending is carried out. Nomenclature � = stress � = strain D = effective elasticity matrix 2 � = minor principal stress 1 � = major principal strain � = principal angle s F = stretch ing force c F = critical collapse load c M = collapse bending moment
