摘要
本文将二维映射动力无穷元进行了合理分类,并讨论了各类无穷元刚度矩阵计算中的敛散性,推导出更有效、更适宜的计算无穷元刚度矩阵的数值积分公式。
In this paper, two-dimensional dynamic infinite elements are reasonably classified, and the-convergence of their stiffness matrices is discussed. A more suitable numerical integral formula for calculation of the element stiffness matrices is presented. A simple example is given to demonstrate the efficiency of the numerical scheme. -
