Abstract EN
Due to the material nonlinearity of hard coating, the coated structure produces the nonlinear dynamical behaviors of variable stiffness and damping, which make the modeling of hard-coating composite structure become a challenging task.
In this study, the polynomial was adopted to characterize this material nonlinearity and an analytical modeling method was developed for the hard-coating composite plate.
Firstly, to relate the hard-coating material parameters obtained by test and the analytical model, the expression of equivalent strain of composite plate was derived.
Then, the analytical model of hard-coating composite plate was created by energy method considering the material nonlinearity of hard coating.
Next, using the Newton-Raphson method to solve the vibration response and resonant frequencies of composite plate and a specific calculation procedure was also proposed.
Finally, a cantilever plate coated with MgO + Al2O3 hard coating was chosen as study case; the vibration response and resonant frequencies of composite plate were calculated using the proposed method.
The calculation results were compared with the experiment and general linear calculation, and the correctness of the created model was verified.
The study shows the proposed method can still maintain an acceptable precision when the material nonlinearity of hard coating is stronger.
