| Abstract: |
| A nonlinear harmonic responses of a composite beam with an arbitrary delamination throngh the width are investigated. The Govening equations including the transverse shear are deduced on basis of the elasticity . The problem is analysized by Galerkin's integration and B\|specimen functions in space as well as the incremental harmonic balance method in time domain. Resonance\|response cures under the harmonic loads are given in an example and demostrate the vibration with basic frequence is still main in nonlinear vibration. |
