| 中文摘要: |
| 研究了具任意脱层复合材料梁的非线性谐波响应问题。基于弹性理论，建立了考虑剪切变形时的复合材料梁脱层的基本方程式。在空间上采用B样条函数和Galerkin积分法，在时间上采用增量谐波平衡法进行计算。通过实例计算，得出了简谐力作用下的非线性动力响应曲线。认为基谐波振动仍是非线性振动的主要部分。 |
| 英文摘要: |
| 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. |
