Estimation of micropolar elastic moduli by inversion of vibrational data
Chiroiu, V. & Munteanu, L. |

| Abstract | |
| A nonlinear wave theory is used to construct an inverse approach for estimation the micropolar elastic moduli of a micropolar plate. The analytical formulation given by this theory is incorporated in a nonlinear minimization algorithm, which minimize the least square "distance" between computed and measured natural frequencies. The minimization algorithm has two steps: a genetic algorithm and a global minimisation procedure (quasi-Newton). Based on the interrelations between natural frequencies and the elastic properties of the material we show that it is possible to reconstruct in a unique manner the unknown micropolar elastic moduli. | |
