The strange mechanics of an elastic rod under null-resultant transverse loads
Davide Bigoni, Diego Misseroni, Andrea Piccolroaz
Two equal and opposite distributed dead loads are applied orthogonally to the axis of an elastic rod in its rectilinear reference configuration, one at the extrados and the other a…
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…
Configurational forces on elastic structures
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…
Hierarchical porosity ihnerited by natural sources affects the mechanical and biological behaviour of bone scaffolds
Simone Sprio, Silvia Panseri, Monica Montesi +8
A 3-D porous apatite scaffold (B-HA), recently obtained through biomorphic transformation of a natural wood, is investigated on its multi-scale porous structure determining superio…
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…
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…
Omnidirectional flexural invisibility of multiple interacting voids in vibrating elastic plates
D. Misseroni, A. B. Movchan, D. Bigoni
In elasticity, the design of a cloaking for an inclusion or a void to leave a vibrational field unperturbed by its presence, so to achieve its invisibility, is a thoroughly analyze…
Experimental investigation of progressive instability and collapse of no-tension brickwork pillars
Massimiliano Gei, Diego Misseroni
The progressive instability behaviour of compressed dry-stone rectangular pillars loaded with an eccentric load is assessed experimentally and compared with the theory. Photoelasti…
Asymptotic self-restabilization of a continuous elastic structure
F. Bosi, D. Misseroni, F. Dal Corso +2
A challenge in soft robotics and soft actuation is the determination of an elastic system which spontaneously recovers its trivial path during postcritical deformation after a bifu…
Flutter and divergence instability in the Pfluger column: experimental evidence of the Ziegler destabilization paradox
Davide Bigoni, Oleg N. Kirillov, Diego Misseroni +2
Flutter instability in elastic structures subject to follower load, the most important cases being the famous Beck's and Pfluger's columns (two elastic rods in a cantilever configu…
Detecting singular weak-dissipation limit for flutter onset in reversible systems
Davide Bigoni, Oleg N. Kirillov, Diego Misseroni +2
A `flutter machine' is introduced for the investigation of a singular interface between the classical and reversible Hopf bifurcations that is theoretically predicted to be generic…
The destabilizing effect of external damping: Singular flutter boundary for the Pfluger column with vanishing external dissipation
Mirko Tommasini, Oleg N. Kirillov, Diego Misseroni +1
Elastic structures loaded by nonconservative positional forces are prone to instabilities induced by dissipation: it is well-known in fact that internal viscous damping destabilize…

A micromechanical approach is set-up to analyse the increase in elastic stiffness related to development of plastic deformation (the elastoplastic coupling concept) occurring durin…
Plastically-driven variation of elastic stiffness in green bodies during powder compaction: Part I Experiments and elastoplastic coupling
L. P. Argani, D. Misseroni, A. Piccolroaz +3
Cold compaction of ceramic powders is driven by plastic strain, during which the elastic stiffness of the material progressively increases from values typical of granular matter to…
The deformation of an elastic rod with a clamp sliding along a smooth and curved profile
D. Misseroni, G. Noselli, D. Zaccaria +1
The design of compliant mechanisms is crucial in several technologies and relies on the availability of solutions for nonlinear structural problems. One of these solutions is given…
