Abstract: B21.00012 : Global inverse design of anisotropiclly deforming sheets using curve defects*
1:42 PM–1:54 PM
James P Sethna
Here we show how the introduction of curve defects alleviates this problem. Demanding that these lines are invisible upon actuation, i.e. carry no gaussian curvature, uniquely determines the smooth director field across the curve, while allowing it to expand beyond the singularity.
