we investigate developable cones (d-cones) topology and mechanical properties. We found that for a sample of a finite thickness the singularity is never pointlike but has a spatial extension in form of a crescent. The variations of the sheet local curvature versus the distance from the d-cone tip for all deformations showed that the d-cone tip is rejected by a distance which depends on the deformation and on the singularity extension. A further deformation of the d-cone leads to a transition to… Expand
