  Experimental analysis of a strong fluid–structure interaction on a soft membrane — Application to the flapping of a yacht downwind sail 

  DEPARDAY, Julien; AUGIER, Benoit; BOT, Patrick (Elsevier BV, 2018-08)

  In the present study we investigate the flapping instability of a light, soft, highly cambered membrane subject to wind loading. An original in-situ experiment is developed where time-resolved pressures and forces are ...

  Unsteady numerical simulations of downwind sails 

  DURAND, Mathieu; HAUVILLE, Frédéric; BOT, Patrick; AUGIER, Benoit; ROUX, Y; LEROYER, Alban; VISONNEAU, Michel (Royal Institution of Naval Architects, 2010-06)

  Modelling the wind, sail and rig interactions on a sailing yacht is a complex subject, because the quality of simulation depends on the accuracy of both structural and fluid simulations which strongly interact. Moreover, ...

  Cryogenic assistance during CFRP drilling 

  DUCROUX, Edouard; MERZOUKI, Johan; ROSSI, Frédéric; POULACHON, Gérard; ABRIVARD, Guillaume (2017-11-04)

  The CFRP cutting mechanisms are highly linked to fibers orientations. Firstly, this paper deals with a mechanical characterization of CFRP under cryogenic temperatures. An instrumented compressive test with fibers oriented ...
