Title GEOMETRICALLY NONLlNEAR ANALYSIS ON WRINKLlNG PHENOMENA OF A CIRCULAR MEMBRANE
Author Takashi Iwasa,M. C. Natori,Hirohisa Noguchi,Ken Higuchi
Summary For quantitative evaluation on wrinkling phenomena of membrane structures�EŒa geometrically nonlinear analysis is carried out. Using mixed interpolation tonsorial components( MITC) shell elements�EŒthe wrinkling phenomena of a circular membrane with a rotation hub are analyzed. The effects of mesh aspect ratio�EŒstep ratio of numerical analysis and shape function of MITC shell elements on wrinkling analysis are discussed�EŒan d dependency of wrinkling phenomena on loading histories is clarified.
