Ph.D. position @ University of Trento (Italy) “New loadings for structural elements and homogenization of elastic periodic materials” within the context of my ERC Advanced Grant project "Beyond hyperelasticity: a virgin land of extreme materials"

1 Ph.D. position (36 months) within the research activity relative to my ERC AdG Grant "Beyond" will be funded by and available at the University of Trento (Italy). The student will be supervised by me and my collaborators Francesco Dal Corso, Diego Misseroni, Andrea Piccolroaz, and Roberta Springhetti. See also the PDF attached.

Structures loaded with a force acting along a fixed straight line, or the “Reut’s column problem”

How to provide a structure with a force lying on a fixed line?
We provide the answer to this question in our paper: Bigoni and Misseroni (2019) Structures loaded with a force acting along a fixed straight line, or the “Reut’s column problem”.
Journal of the Mechanics and Physics of Solids.

Configurational forces and nonlinear structural dynamics

How a mass falls when attached to a flexible element with varying length?

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
