摘要
自然单元法既具有无网格方法和经典有限元方法的优点又克服了两者的一些缺点,为水工结构分析开拓了新途径.编制了弹性自然单元法C++程序SGNEM1.0,利用其对几个水工结构物进行分析,通过和有限元分析结果进行比较分析,结果表明自然单元法在水工结构数值分析上的应用是可行的.
The elastic natural element is a promising element-free method appeared recently,many scholars have paid attention to the method.The analysis program SGNEM1.0 in C++ is developed in order to bring forth the approach used to analyze the hydraulic structures,and the results of a few examples using this program are compared with FEM.From these it can conclude that the NEM is valid to the numerical analysis of hydraulic structure.
