Dynamically triggered snap-through
Gregory Kozyreff, Lucie Domino, Basile Radisson +1
Snap-through is a sudden and large mechanical deformation that is usually triggered by driving a control parameter beyond a bifurcation threshold. Here, we study a buckled strip th…
Elastic snap-through instabilities are governed by geometric symmetries
Basile Radisson, Eva Kanso
Many elastic structures exhibit rapid shape transitions between two possible equilibrium states: umbrellas become inverted in strong wind and hopper popper toys jump when turned in…
Dynamic behavior of elastic strips near shape transition
Basile Radisson, Eva Kanso
Elastic strips provide a canonical system for studying the mechanisms governing elastic shape transitions. Buckling, linear snap-through, and nonlinear snap-through have been obser…
The θ-formulation of the 2D elastica -- Buckling and boundary layer theory
Gregory Kozyreff, Emmanuel Siéfert, Basile Radisson +1
The equations of a planar elastica under pressure can be rewritten in a useful form by parametrising the variables in terms of the local orientation angle, , instead of the arc…
