The phenomenon of oscillatory instability called 'flutter'was observed in aeroelasticity and
rotor dynamics about a century ago. Driven by a series of applications involving non …

It is shown that a compound elastic structure, which displays a dynamic instability, may be
designed as the union (or 'fusion') of two structures which are stable when separately …

Application of a dead compressive load at the free end of an elastic rod (the 'blade') induces
its penetration into a sliding sleeve ending with a linear elastic spring. Bifurcation and …

This paper explores the use of simultaneous tensile buckling of unit cells to induce a
transformation in lattice topology. Under tension, unit cells undergo passive transformation …

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 …

This paper deals with a concept for a reconfigurable structure bio-inspired by the cell wall
architecture of euglenids, a family of unicellular protists, and based on the relative sliding of …

In the past few decades, several concepts for morphing wings have been proposed with the
aim of improving the structural and aerodynamic performance of conventional aircraft wings …

In this paper, we investigate the instability behavior of thin elastic circular disks subjected to
two concentrated edge loads arranged along a diameter. Despite the determination of …

The theory of the planar elastica is presented in detail and is used to illustrate problems of
buckling of a slender structure under tensile dead loading, of buckling as related to …

Structures have traditionally been designed to work below their critical load, because any
instability was normally identified as connected to failure or loss of functionality. Instability …
