有限单元法应力分析程序国内已十分普遍,然而在工程实践中推广和应用仍有不少困难,其中主要是单元划分、信息填写、荷载转置等大量地极易出错的手工工作,因此,除了结构十分复杂,用传统方法计算感到困难时,才用有限单元法外,对一般结构,设计者仍乐于采用传统方法。武汉水院等单位从数学观点出发,对任意平面域自动划分三角形单元编写了程序,
The finite element method stress analysis program is very common in China. However, there are still many difficulties in the promotion and application in engineering practice. The main ones are unit division, information filling, load transposition, and a large number of easily error-prone manual work. Therefore, in addition to The structure is very complex. When the calculation is difficult with the traditional method, the finite element method is used. For the general structure, the designer is still happy to adopt the traditional method. Wuhan Water Institute and other units prepared procedures for automatically dividing triangular elements into arbitrary plane domains from the viewpoint of mathematics.
