Complex Orthogonal Decomposition (C.O.D.) using Python
Marc Vacher, Stéphane Perrard, Sophie Ramananarivo
This work presents the application of the Complex Orthogonal Decomposition (C.O.D.) to a simple spatio-temporal signal. C.O.D. has been introduced rst in the article of B. Feeny, e…
Tunable Thin Elasto-Drops
Antonin Eddi, Stéphane Perrard, Jishen Zhang
We present an experimental method to fabricate centimetric thin elastic capsules with highly uniform thickness and negligible bending stiffness using silicone elastomers. In our ex…
High-resolution measurement of sea ice mechanical characteristics using Distributed Acoustic Sensing
Sébastien Kuchly, Ludovic Moreau, Vasco Zanchi +6
Sea ice mechanical properties are involved in dynamical processes acting from the scale of meters to several hundred kilometers. The current rapid changes in the state of polar sea…
Wave induced fracture of a sea ice analog
Baptiste Auvity, Laurent Duchemin, Antonin Eddi +1
We study at the laboratory scale the rupture of thin floating sheets made of a brittle material under a wave-induced mechanical forcing. We show that the rupture occurs where the c…
Resonance of an object floating within a surface wavefield
Sébastien Kuchly, Wilson Reino, Kyle McKee +3
We examine the interaction between floating cylindrical objects and surface waves in the gravity regime. Since the impact of resonance phenomena associated with floating bodies, pa…
Large-Scale Turbulent Pressure Fluctuations Revealed by Ned Kahn's Artwork
Jishen Zhang, Stéphane Perrard
We investigate the dynamics of pendulum chains immersed in turbulent boundary layers. We combine laboratory experiments and video analysis of the kinetic facade exhibits by the art…
