We study the packing of a large number of congruent and non-overlapping circles inside a
regular polygon. We have devised efficient algorithms that allow one to generate …

We investigate the load transmission along an elastic rod of finite cross-section in contact
with a rigid cylinder, as system often referred to as the generalized capstan problem. In the …

Crumpling and folding of paper are at first sight very different ways of confining thin sheets in
a small volume: the former one is random and stochastic whereas the latest one is regular …

We present PolyHoop, a lightweight standalone C++ implementation of a mechanical model
to simulate the dynamics of soft particles and cellular tissues in two dimensions. With only …

NiTi porous materials with unprecedented superelasticity and shape memory were
manufactured by self-entangling, compacting and heat treating NiTi wires. The versatile …

A laterally confined thin elastic sheet lying on a liquid substrate displays regular undulations,
called wrinkles, characterized by a spatially extended energy distribution and a well-defined …

The morphology of an elastic strip subject to vertical compressive stress on a frictional rigid
substrate is investigated by a combination of theory and experiment. We find a rich variety of …

We investigate the morphologies and maximum packing density of thin wires packed into
spherical cavities. Using simulations and experiments, we find that ordered as well as …

Abstract Space-saving design is a requirement that is encountered in biological systems and
the development of modern technological devices alike. Many living organisms dynamically …

We show that the statistical properties of a vibrated granular bead chain are similar to
standard models of polymers in equilibrium. Granular chains of length up to N= 1024 beads …
