Abstract :
Dynamic stability of viscoelastic elements of thin-shelled constructions under interaction with flow of fluid or gas is studied. The definition of viscoelastic body´s stability corresponds to Liapunov´s concept of dynamical system´s stability. Have been considered the following problems: problem about dynamics of elements of a plane channel, through which fluid flows; of elements of a wing profile; of elements of a facilitated weight wing
