基于Schapery三维粘弹性损伤增长本构关系，建立了含横向基体裂纹的单向纤维增强粘弹性复合材料板的损伤模型。应用Karman理论，建立了粘弹性复合材料板在横向周期载荷作用下的非线性动力学控制方程。在空间域采用有限差分法，在时间域采用Newton-Newmark法，通过迭代求解积分-偏微分控制方程。文中给出了一些算例，并将计算结果与已有数据进行了比较.
Based on the Schapery three-dimensional viscoelastic constitutive relationship with growing damage, a damage model with transverse matrix cracks for the unidirectional fibre reinforced viscoelastic composite plates is developed. By using Karman theory, the nonlinear dynamic governing equations of the viscoelastic composite plates under transverse periodic loading are established. By applying the finite difference method in spatial domain and the Newton-Newmark method in time domain, and using the iterative procedure, the integral-partial differential governing equations are solved. Some examples are given and the results are compared with available data.
