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…
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…
Configurational forces and nonlinear structural dynamics
Costanza Armanini, Francesco Dal Corso, Diego Misseroni +1
Configurational, or Eshelby-like, forces are shown to strongly influence the nonlinear dynamics of an elastic rod constrained with a frictionless sliding sleeve at one end and with…
Nested Bloch waves in elastic structures with configurational forces
Francesco Dal Corso, Domenico Tallarico, Natalia V. Movchan +2
Small axial and flexural oscillations are analyzed for a periodic and infinite structure, constrained by sliding sleeves and composed of elastic beams. A nested Bloch-Floquet techn…
Identification of second-gradient elastic materials from planar hexagonal lattices. Part II: Mechanical characteristics and model validation
G. Rizzi, F. Dal Corso, D. Veber +1
Positive definiteness and symmetry of the constitutive tensors describing a second-gradient elastic (SGE) material, which is energetically equivalent to a hexagonal planar lattice…
