A nonlinear model of shearable elastic rod from an origami-like microstructure displaying folding and faulting
M. Paradiso, F. Dal Corso, D. Bigoni
A new continuous model of shearable rod, subject to large elastic deformation, is derived from nonlinear homogenization of a one-dimensional periodic microstructured chain. As part…
The elastica sling

The nonlinear mechanics of a flexible elastic rod constrained at its edges by a pair of sliding sleeves is analyzed. The planar equilibrium configurations of this variable-length e…
Elastic solids under frictionless rigid contact and configurational force
Francesco Dal Corso, Marco Amato, Davide Bigoni
A homogeneous elastic solid, bounded by a flat surface in its unstressed configuration, undergoes a finite strain when in frictionless contact against a rigid and rectilinear const…
Flutter instability in solids and structures, with a view on biomechanics and metamaterials
Davide Bigoni, Francesco Dal Corso, Oleg N. Kirillov +3
The phenomenon of oscillatory instability called \lq flutter' was observed in aeroelasticity and rotor dynamics about a century ago. Driven by a series of applications involving no…
Stabilization against gravity and self-tuning of an elastic variable-length rod through an oscillating sliding sleeve
Panagiotis Koutsogiannakis, Diego Misseroni, Davide Bigoni +1
An elastic rod, straight in its undeformed state, has a mass attached at one end and a variable length, due to a constraint at the other end by a frictionless sliding sleeve. The c…
Non-smooth dynamics of buckling based metainterfaces: rocking-like motion and bifurcations
Nikolin Hima, Francesco D' Annibale, Francesco Dal Corso
The non-smooth dynamics is investigated for an elastic planar metainterface composed by two layers of buckling elements, each one allowing motion on one side only. Through the anal…

Davide Bigoni, Federico Bosi, Francesco Dal Corso +1
The discovery of configurational forces acting on elastic structures and its initial applications are reviewed. Configurational forces are related to the possibility that an elasti…
Double restabilization and design of force-displacement response of the extensible elastica with movable constraints
Panagiotis Koutsogiannakis, Davide Bigoni, Francesco Dal Corso
A highly deformable rod, modelled as the extensible elastica, is connected to a movable clamp at one end and to a pin sliding along a frictionless curved profile at the other. Bifu…
Buckling vs unilateral constraint for a multistable metamaterial element
Nikolin Hima, Davide Bigoni, Francesco Dal Corso
A structural element is designed and investigated, forming the basis for the development of an elastic multistable metamaterial. The leitmotif of the structural design is the imple…
Non-holonomic constraints inducing flutter insability in structures under conservative loadings
Alessandro Cazzolli, Francesco Dal Corso, Davide Bigoni
Non-conservative loads of the follower type are usually believed to be the source of dynamic instabilities such as flutter and divergence. It is shown that these instabilities (inc…
Elastica catastrophe machine: theory, design and experiments
Alessandro Cazzolli, Diego Misseroni, Francesco Dal Corso
The theory, the design and the experimental validation of a catastrophe machine based on a flexible element are addressed for the first time. A general theoretical framework is dev…
