We first probe the effects of actuation patter ns on the dynamic response of plates with different mechanical and geometr ical properties. In particular\, we consider the actuation using a distrib uted internal moment that represents the actuation of piezoelectric smart materials and compare the hydrodynamic performance of such plates with the hydrodynamics of a plunging elastic plate. We then examine the combined p late actuation that integrates plunging using an external actuator with in ternal piezoelectric actuation. We search for hydrodynamic regimes in whic h the synergy of two different actuation modes leads to improved thrust pr oduction and efficiency. Furthermore we probe how passive attachments to a ctive plates\, including attachments with tapered geometry\, can be harnes sed to enhance the thrust production and efficiency. Finally\, we study ho w complex actuation patterns integrating external and internal actuations can be used for navigation and maneuvering of robotic swimmers.\nErsan Dem irer\, Georgia Institute of Technology\, USA CATEGORIES:Interdisciplinary online seminar series on Biolocomotion END:VEVENT BEGIN:VTIMEZONE TZID:Europe/Paris X-LIC-LOCATION:Europe/Paris BEGIN:DAYLIGHT DTSTART:20200329T030000 TZOFFSETFROM:+0100 TZOFFSETTO:+0200 TZNAME:CEST END:DAYLIGHT END:VTIMEZONE END:VCALENDAR
