Abstract：

In finite element software exploitation,the reuse and the efficiency of program modules are two key issues which affect the software performance.In order to resolve reuse problems,object-oriented language can be used to develop finite element stiffness matrix calculation procedures.Using reference variable,dynamic memory allocation function-calloc function and inline function can increase the efficiency of element matrix calculation.Element stiffness matrix which was compiled by using C++ language was introduced.Compared with finite element program with traditional fortran language,the program with OOP has predominance of high speed in program running,convenience in maintenance and easily realizing coexisting of various kinds of elements.It is effective for large scale finite element program design.Finally,through the use of comparative examples,the efficiency of this kind of matrix was illustrated.
