Original abstract
This contribution is focused on the analysis if dynamic behavior of elastic continuum moving in liquid. The method solution is demonstrated on the non-stationary movement of a bar in a real, incompressible liquid. The principle of the solution is based on the modal transformation of the bar and discrete process using the finite element method. The problem is in general non-linear. However, the method introduced in this contribution allows the solution of the problem in time steps. The solution is based upon a certain substitution which provides gradual separation of the movement of liquid and the movement of the bar. This substitution is entered analogously on the finite element and is dependent on the normal coordinates. The result is a tensor of additional effects.
