Department of Mathematics - Seminar on Applied Mathematics - Capillary folding of thin elastic sheets
Capillary folding is the process of folding planar objects into three-dimensional (3D) structures using capillary force. We propose a 3D model for the capillary folding of thin elastic sheets with pinned contact lines.
