- Abstract
- The article demonstrates the solution of the problem for determining the energy dissipation characteristics of the layers from energy dissipative properties of composites laminates with the aid of the identification method. An energy structural-phenomenological model by Zinoviev - Ermakov is applied as the energy dissipation model in CM under vibrations. Apparent advantages can be obtained with the use of the identification procedure of all characteristics of the layers from the results of simple (standard) tests of CM with various reinforcing structures. The advantages of the proposed approach are shown in the analysis of experimental data of a carbon fiber reinforced plastic. The feature of the present paper is an analysis for stability of computed values of layers characteristics to random deviations in experimental initial data.
