基于von Karman板理论,利用三分区模型,建立了在面内压力和横向荷载联合作用下具脱层的轴对称正交层合圆板的非线性运动微分方程,其中,考虑了横向剪切效应和脱层接触效应.在此基础上,利用正交配.点法进行了求解,并着重讨论了脱层之间的接触效应对结构非线性动力响应的影响.
Based on the von Karmen plate theory and the three region model, the nonlinear governing equations of an axisymmetricly delaminated circular plate are established with faking into account the effect of transverse shear as well as contact between of delaminated surfaces. The dynamic responses of the axisymmetricly delaminated circular plate are solved out by using the orthogonal point collocation method, and the effect of contact on the nonlinear dynamic response of delaminated plates is analyzed in detail.
