| Abstract: | The principles and methods of computer simulation for the deformation of mirror surface and the stress distribution of mirror were established by the use of the tri-axial elastic mechanics and finite element method of structural strength analysis, and the experimental results were obtained. Depending on the theories and techniques, the stress distribution and the place of maximum stress, and the deformation of mirror surface for tetrahedroid mirror were worked out. The computing values were compared with the expeimental results. |
