一边简支二边固支对称三角形板的弯曲

杂形板弯曲问题的准确解是薄板理论中的难题之一，作者以前应用三角级数加多项式的方法解决了悬臂对称三角形板在均布载荷作用下的弯曲问题，在这篇论文中，作者再次应用该方法首次获得了一边简支二边固支对称三角形板在均布载荷作用下弯曲问题的准确解，所获得的解满足微分方程和所有的边界条件，计算方法具有良好的收敛性。

Bending of Symmetric Triangular Plate Possessing a Simply Supported Edge and Two Clamped Edges

In the theory of thin plate,the bending of plates of various shapes is considered as one of the difficult problems.The authors used the method of trigonometric series and polynomial to solve the problem for the bending of a cantilever plate in a symmetric triangular shape under uniform load.This method is also used to get an accurate solution for the bending of a symmetric triangular plate with boundaries of one simply supported edge and two clamped edges,under uniform load. The solution satisfies the differential equation and boundary conditions.Calculations show that the method is of good convergence.
