Wrinkling on stretched circular membranes under inplane torsion -Comparison between bifurcation analysesand experiments-

摘要

It this paper finite element analyses of wrinkling on membranes are carried out, and the results are compared with the results of our experiments. An illustrative example is stretched circular membrane under inplane torsion, which is a classical problem in the study of wrinkling. Wrinkling is considered as a bifurcation phenomenon. It is analyzed by using four-node membrane finite elements considering geometrical nonlinearity. Both isotropic and orthotropic membranes are treated. Membranes are assumed to be elastic.
