Parametric excitation of rotational soft modes of the buckled discrete elastic ring
Panagiotis Koutsogiannakis, Massimo Ruzzene
In the present study, we explore the existence and characteristics of a rotating vibrational mode in a discrete buckled ring that manifests under transverse harmonic forcing. The s…
A simple yet effective ALE-FE method for the nonlinear planar dynamics of variable-length flexible rods
Panagiotis Koutsogiannakis, Theodosios Papathanasiou, Francesco Dal Corso
With recent advances in variable-length structures for use in soft actuation, energy harvesting, energy dissipation and metamaterials, the mathematical modelling and numerical simu…
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…
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…
A numerical study of the run-up and the force exerted on a vertical wall by a solitary wave propagating over two tandem trenches and impinging on the wall
Gerassimos A. Athanassoulis, Constantinos P. Mavroeidis, Panagiotis E. Koutsogiannakis +1
The propagation and transformation of water waves over varying bathymetries is a subject of fundamental interest to ocean, coastal and harbor engineers. The specific bathymetry con…
