| Abstract: |
| For the coupling analysis of structure media and non correlated elastic plastic stress strain relation, non symmetrical structural canonical matrix is often obtained. Traditionally, this matrix is changed to symmetrical matrix by the symmetrization method and error is caused inevitably. With the development of computer technique, direct solution for non symmetrical structural canonical equations is adopted. Because of the limit of computer memory, many complicated and big structural can not be solved. This paper presents a subpart solution tactics for non symmetrical structural canonical equations. Its programming is realized in JIGFEX programming system. The solving capability and applying scope of this system are enhanced greatly. |
