有限元非节点连接方法与刚臂技术的比较

The comparison of the non-nodal connection method and the steel-arm method

介绍了有限元非节点连接方法与刚臂技术,通过比较,得出非节点连接方法是一种适用范围更广的有限元方法.算例利用非节点连接方法进行数值计算并与解析解相比较,验证了非节点连接方法的正确性和准确性.

In this paper, the non-nodal connection method and the steel-ann method are introduced. According to the comparison of the two methods, there is a result that the non-nodal connection method is a more widespread method of limited elements. Through the comparison of the numeric computation with the non-nodal connection method and the numeric reanlts with the analytic results, the correctness and accuracy of the technique is verified and its convenience is demonstrated.
