| Annotation | Dynamics and stability of an elastic element of a wall of a flow channel with a subsonic stream of gas or liquid in it is investigated. Analytical research on stability is conducted on the basis of creation of positive-definite functional. The sufficient stability conditions are obtained. Numerical research of dynamics and stability is conducted on the basis of finite difference method with subsequent realization of numeral experiment on C++. |
