Author Takashi Iwasa,M. C. Natori,Hirohisa Noguchi,Ken Higuchi
Summary For quantitative evaluation on wrinkling phenomena of membrane structuresĀEĆa geometrically nonlinear analysis is carried out. Using mixed interpolation tonsorial components( MITC) shell elementsĀEĆthe wrinkling phenomena of a circular membrane with a rotation hub are analyzed. The effects of mesh aspect ratioĀEĆstep ratio of numerical analysis and shape function of MITC shell elements on wrinkling analysis are discussedĀEĆan d dependency of wrinkling phenomena on loading histories is clarified.
