| Abstract: |
| The code DDJTJQ is a general purposed finite element program, which is developed by Research Institute of Engineering Mechanics of Dalian University of Technology in China, for static and buckling analysis of the engineering structures. The program is coded in Fortran 77 and implemented on the microcomputers. Many advances have been made in the program since its initial version was appraized on the certificate mealing organized by the Ministry of Aerospace Industry of the People's Republic of China in October 1986. The program has been used to analyze many engineering structures such as the complex stiffened plates and shells, practice rocket structures, reticulated shell structures, huge vacuum tank,containers of large scale power transformers, and so on. In this paper, the capabilities and the features, the capacity of the program are introduced. The numerical results of three engineering structures are given to illustrate the application of the DDJTJQ. Now the code is transposed to SUN 4/490 work station and used the statis and buckling analysis of the toroidal shell with 14300 D. O. F and the cylindrical shell with 28656 D. O. F. |
