| 摘 要： | 结构计算中会采用多种类型单元对同一结构进行计算.传统的结构有限元计算大多采用FORTRAN语言进行编程,由于无法实现多态性的混合单元计算,所以对多类型单元程序相当复杂.将C语言中空指针思想应用于结构有限元分析,从而用简单的C语言实现了不同类型单元的混合编号、自动分类型进行刚度矩阵计算等复杂的多态性功能.首先提出在C语言...

| Abstract: | Multi-type units is often used to calculate the same structure in structure calculation.Programmed by FORTRAN language,and incapable of realizing polymorphism mixed units calculation,the traditional fem analysis of structure is very complicated for multi-type units program.By use of null pointer thought in C language,the complex polymorphism feature including the fixedly numbering of different type units,the calculation of stiffness matrix by spontaneously classifying model is achieved with simple C languag... |
