Wrinkling Of Membrane And Thin Film Under Torsion, Tingting Chen

Dissertations and Theses

Membranes and thin film structures are widely used in modern technologies. Applications include solar sails and sunshields in space missions, biological membranes and flexible circuit boards. Wrinkling of membrane or a stiff film on a soft substrate may occur in either desired or unwanted patterns. This work tries to obtain some understanding on the wrinkling phenomenon and provide guidance in avoiding wrinkling or effectively controlling the wrinkle patterns.

Many works have been published about wrinkling in the thin sheets since the 20^th century. However, there is no simple analytical way to systematically characterize the wrinkling in these studies. In …
