Abstract (2. Language): 
The paper presents an analysis of the damping of laminated materials with four different stacking sequences. The impulse technique was chosen to perform modal analysis of the ease of implementation and quickness of the test. The numerical analysis is performed by the finite element method using beam element. The results obtained are compared with the experimental responses in frequency of the structure. The decrease in frequency for different rates of loading shows the loss of stiffness for all studied materials. The structural damping of the different beams is extracted from a finite element modelling and evaluated from a handling of damaged and undamaged modal energies.
