| 摘 要： | 采用Timoshenko几何变形假设，应用黏弹性厚板几何非线性的分析方法，推导了黏弹性损伤中厚板的几何非线性问题的动力学方程．它是一个五元非线性积分——偏微分方程组．当不考虑损伤时，此方程可以退化得到黏弹性中厚板的非线性动力方程。

| Abstract: | A set of geometric nonlinear dynamic equations for mid-thick viscoelastic plates with damage is derived by adopting the Timoshenko geometric deformation theory and analysis method of geometric nonlinear for thick viscoelastic plates. This set of the equations is of nonlinear integral-partial differential equations with five unknown functions. It can be simplified into the set of dynamic equations for mid-thick viscoelastic plates as the damage is neglected. |
