Description	The project focuses on the improvement of current and development of new methods for numerical simulations of flow induced vibrations of elastic structures in post-critical states after loosing the system stability, when the deformations are large and the system is nonlinear. The post-flutter behavior of a vibrating structure (e.g. airfoil or human vocal fold) in interaction with 2D and 3D incompressible or compressible viscous flow will be modeled. The numerical simulation consists of the finite element and finite volume solution of Navier-Stokes equations together with various turbulence models and coupled with the differential equations describing the structure motion. The time dependent computational domain and a moving grid will be taken into account with the aid of the Arbitrary Lagrangian-Eulerian (ALE) formulation for large displacements of the structure. The computed results will be partially verified by linear approximations. Experimental studies of post-critical behavior of structures can be destructive and the numerical simulations may foresee such dangerous situations.The project focuses on the improvement of current and development of new methods for numerical simulations of flow induced vibrations of elastic structures in post-critical states after loosing the system stability, when the deformations are large and the system is nonlinear.

Chování vibrujícího tělesa (např. leteckého profilu nebo lidské hlasivky) bude modelováno po ztrátě aeroelastické stability (flutter) při interakci tělesa s 2D a 3D nestlačitelným i stlačitelným prouděním viskózní tekutiny. Numerické simulace spočívají v řešení Navier-Stokesových rovnic metodou konečných prvků a objemů spolu s různými modely turbulence a vázanými diferenciálními pohybovými rovnicemi tělesa. Časově závislá výpočetní oblast a pohyblivá síť bude vzata v úvahu užitím ALE (Arbitrary Lagrangian-Eulerian) formulace pro velké výchylky tělesa. Vypočtené výsledky budou částečně ověřovány lineárními aproximacemi. Experimentální výzkum pokritických stavů může vést k destrukcím těles a numerické simulace mohou takové nebezpečné situace předvídat.
