由考虑界面的损坏并且用变化原则的效果,有界面的损坏的把压成薄片的盘子的三维的非线性的动态管理方程向精确压力分析基于一般 six-degrees-of-freedom 塔板理论被导出。为有界面的损坏的一个简单地支持的把压成薄片的盘子的 interlaminar 应力和非线性的动态反应的答案被使用有限差别方法获得,并且结果被比较与非线性的有限元素方法的答案验证。在数字计算,在接口和把压成薄片的盘子的非线性的动态反应的压力上的界面的损坏的效果被讨论。
By considering the effect of interfacial damage and using the variation principle, three-dimensional nonlinear dynamic governing equations of the laminated plates with interfacial damage are derived based on the general sixdegrees-of-freedom plate theory towards the accurate stress analysis. The solutions of interlaminar stress and nonlinear dynamic response for a simply supported laminated plate with interfacial damage are obtained by using the finite difference method, and the results are validated by comparison with the solution of nonlinear finite element method. In numerical calculations, the effects of interfacial damage on the stress in the interface and the nonlinear dynamic response of laminated plates are discussed.
