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…
Flutter instability and Ziegler destabilization paradox for elastic rods subject to non-holonomic constraints
Alessandro Cazzolli, Francesco Dal Corso, Davide Bigoni
Two types of non-holonomic constraints (imposing a prescription on velocity) are analyzed, connected to an end of a (visco)elastic rod, straight in its undeformed configuration. Th…
Dynamics of prestressed elastic lattices: homogenization, instabilities, and strain localization
Giovanni Bordiga, Luigi Cabras, Andrea Piccolroaz +1
A lattice of elastic Rayleigh rods organized in a parallelepiped geometry can be axially loaded up to an arbitrary amount without distortion and then be subject to incremental time…
Structures loaded with a force acting along a fixed straight line, or the "Reut's column problem"
Davide Bigoni, Diego Misseroni
An elastic double pendulum subject to a force acting along a fixed straight line, the so-called "Reut's column problem", is a structure exhibiting flutter and divergence instabilit…
Bifurcation of elastic solids with sliding interfaces
D. Bigoni, N. Bordignon, A. Piccolroaz +1
Lubricated sliding contact between soft solids is an interesting topic in biomechanics and for the design of small-scale engineering devices. As a model of this mechanical set-up,…
Incremental constitutive tensors and strain localization for prestressed elastic lattices: Part I -- quasi-static response
G. Bordiga, L. Cabras, A. Piccolroaz +1
A lattice of elastic rods organized in a parallelepiped geometry can be axially loaded up to an arbitrary amount without distortion and then be subject to incremental displacements…
