Snaking elastic rods

How can an elastic rod model snake motion?

An elastic rod constrained in a perfectly smooth and rigid channel can move through a release of elastic energy and the development of a configurational force.

Elastica compass, catapult and soft robot arm

When an elastic rod with a rotating clamp behaves as a deformable compass or as a deformable catapult?

This behaviour depends on the load applied at the free end!!

The injection of an elastic rod

What should be expected when an elastic rod is forced to slip inside a sliding sleeve and against an obstacle?

After buckling, configurational forces play a strong role, so that a force reversal is observed!

Can an elastic rod attain self-encapsulation when loaded transversally at midspan?

Can an elastic rod attain self-encapsulation when loaded transversally at midspan?

The elastic rod assumes the form of a liquid drop at self-encapsulation!

What are the boundary conditions of an elastic rod at a clamp moving on a perfectly smooth and rigid circular profile?

What are the boundary conditions of an elastic rod at a clamp moving on a perfectly smooth and rigid circular profile?

The tangential shear at the clamp turns out to not be null!

Torsional locomotion

Can a torque induce longitudinal motion of an elastic rod?

See the explanation and an example of use of the 'torsional gun' at http://www.ing.unitn.it/~bigoni/torsional_locomotion.html

Elastica arm scale

Can configurational forces be exploited to design a new type of scale?

Can an elastic structure buckle under tensile dead load?

We all know Euler buckling of a beam under axial thrust, but can buckling occur in an elastic structure in which all elements are subject to tensile dead loading?

We provide a positive answer to this question, see http://www.youtube.com/user/RoyalSociety#p/u/0/EKngs1vvcJU
