Force focusing in confined fibers and sheets
Victor Romero, Enrique Cerda, T. A. Witten +1
A thin fiber or sheet curled into a circular container has a detached region whose shape and force ratios are independent of material properties and container radius. We compute th…
Numerical Investigation of Isolated Crescent Singularity
Tao Liang
In this paper we examine numerically the properties, especially the scaling properties, of an isolated crescent singularity similar to that of a developable cone. The desired isola…
Spontaneous curvature cancellation in forced thin sheets
Tao Liang, Thomas A. Witten
In this paper we report numerically observed spontaneous vanishing of mean curvature on a developable cone made by pushing a thin elastic sheet into a circular container. We show t…
Crescent Singularities in Crumpled Sheets
Tao Liang, Thomas A. Witten
We examine the crescent singularity of a developable cone in a setting similar to that studied by Cerda et al [Nature 401, 46 (1999)]. Stretching is localized in a core region near…
