TI - Analysis of Wrinkling Behavior of Anisotropic Membrane T2 - Computer Modeling in Engineering \& Sciences PY - 2004 VL - 6 IS - 4 SN - 1526-1506 AB - This paper presents the development and evaluation of a wrinkling analysis procedure for anisotropic membranes. The procedure is based on a penalty-parameter modified material model and a non-linear root finding to simulate the uni-axial stress state. The procedure was implemented in the ABAQUS finite element code as a user subroutine, and then applied to annular and square membranes. The wrinkle problems were also solved by shell element post-buckling analysis and the results were compared. The effect of anisotropy and unsymmetric loading on the wrinkling behavior was investigated. KW - Membrane KW - wrinkle KW - anisotropic KW - penalty-parameter DO - 10.3970/cmes.2004.006.397
