摘要
借助有限元几何插值的思想 ,利用结点的坐标和插值函数表示单元内任一点的坐标 ,根据插值函数的性质 ,给出了平面图形几何性质计算的一种方法 ,该方法易于编程计算 ,对于直边边界的区域可以给出精确结果。将该方法用于鱼尾板的几何性质计算。
Based on the geometric interpolation function of constant strain element (CST) of finite element method, a new method for the evaluation of geometric properties of plane geometry is presented. This approach can be easily implemented in computer program. It is demonstrated from numerical implementation that the proposed procedure is accurate and efficient.
