各位老师好，Journal of fluids and structures杂志主编Emmanuel de Langre教授将于4月10日上午9：40在船海楼1014会议室介绍Journal of fluids and structures杂志，并做题为Does flexibility always reduce drag of flexible structures?的学术讲座，欢迎各位老师参加。

Academic Lecture Title: Does flexibility always reduce drag of flexible structures?

Summary

The static reconfiguration of flexible systems exposed to transverse flows is classically known to reduce the drag these structures have to withstand. But the more a structure bends, the more parallel to the flow it becomes, and flutter instability may increase drag or stress inside the system. This may become more complex when the flow is oscillatory, or when vortex-induced vibrations are considered. This very generic issue is explored on simple beam and blade-like systems.

CV of Professor Emmanuel de Langre

Emmanuel de Langre is a Professor of Mechanics in Ecole Polytechnique, Paris, France. He received his Ph.D. in Fracture Mechanics in 1984 and then worked until 1997 as an engineer in the French nuclear industry. He then joined Ecole Polytechnique to start a group on fluid-structure interactions. He is presently the Chief Editor of the Journal of Fluids and Structures. His present research interests are in the broad field of fluid-structure interaction (FSI) and include plant bio-mechanics, energy harvesting based on FSI, vortex-induced vibrations, wind effects and aeroelasticity.
