复杂边界条件正交异性层合板的弯曲

Bending Analysis of Orthogonal Laminated Plates with Complex Boundary Conditions

采用加权残值法分析综合边界条件和混合边界条件的对称正交铺设层合板的弯曲问题。文中取双样条函数为位移试函数,并在边界条件不连续点引入半结点配点的概念,分析了边界条件和权值对挠度和内力的影响。所得结论可供工程实际参考。

In this paper,the method of weighted residuals is used for analysing the symmetric orthogonal laminated plates. By taking double spline functions as the trial functions, and the seminodes of the spline as the additional collocation points,the effects of mixed and complex boundary conditions are analyzed. The results obtained can be used for reference in engineering practice.
