摘要
采用曲线差分法解考虑横向剪切变形的厚板弯曲问题,在同样网格情况下,与普通差分法相比,具有较高的精度。本文利用曲线差分法的基本原理,推导了厚板方程式的曲线差分格式,并通过典型算例与有限差分法、级数解法进行了比较。
In this paper, the Solution for rectangular thick plates in consideration of shear deformation by means of curvilinear finite difference method is presented. In case of the same net, this method has a better accuracy than the general finite difference method. Difference form of equations for thick plates by means of curvilinear finite difference method is derived. This method, is compared with both of the finite difference method and the series method through typical examples.
