EML Special Issue on 3D Assembly by Cutting, Bending and Folding

When patterned with different materials, gradients or cut-outs, thin structures such as sheets and rods can bend or fold either spontaneously or by actuation in response to a force or stimulus to form a pre-designed three dimensional structure. This special issue addresses the design and mechanics of these structures with a special emphasis on programmability and non-linearity.

Post-doctoral position at Univ. Pittsburgh: soft tissue buckling

A post-doctoral position is available in the lab of Sachin Velankar at the University of Pittsburgh to conduct experimental research on buckling of soft tissues in cephalopods (octopus or cuttlefish).

Intrinsically anomalous self-similarity of randomly folded matter

We found that randomly folded thin sheets exhibit unconventional scale invariance, which we termed as an intrinsically anomalous self-similarity, because the self-similarity of the folded configurations and of the set of folded sheets are characterized by different fractal dimensions. Besides, we found that self-avoidance does not affect the scaling properties of folded patterns, because the self-intersections of sheets with finite bending rigidity are restricted by the finite size of crumpling creases, rather than by the condition of self-avoidance.
