Adiabatic Lamb modes in 3D tapered waveguides: Cut-off effects and ZGV resonances
Alexandre Yoshitaka Charau, Jérôme Laurent, Tony Valier-Brasier
This paper aims to enhance our understanding of the physical behavior of adiabatic modes in inhomogeneous elastic plates, particularly their remarkable capacity to adapt to gradual…
Tunneling of Elastic Waves in a Tapered Waveguide
Alexandre Yoshitaka Charau, Jérôme Laurent, Tony Valier-Brasier
Understanding how evanescent modes mediate energy transfer in tapered elastic waveguides is of paramount interest, as it unlocks new strategies for wave control and manipulation. E…
Validation of a model for an ionic electro-active polymer in the static case
Mireille Tixier, Joël Pouget
IPMCs consist of a Nafion(R) ionic polymer film coated on both sides with a thin layer of metallic electrodes. The polymer completely dissociates when it is saturated with water, r…
Validation of a model for an electro-active polymer
Mireille Tixier, Joël Pouget
Ionic electro-active polymers (EAP) are able to deform under the action of an electric field, which confers them many applications as sensor, actuator or energy recovery.An ionic m…
Modeling of the bending of an electroactive polymer strip
Mireille Tixier, J Pouget
Ionic electro-active polymer (Nafion for example) can be used as sensor or actuator. To this end, a thin film of the water-saturated material is sandwiched between two electrodes.…
Recovering the normal form of an elasticity tensor
Sophie Abramian, Boris Desmorat, Rodrigue Desmorat +2
We propose an effective geometrical approach to recover the normal form of a given Elasticity tensor, once we know its symmetry class. In other words, we produce a rotation which b…
