| Abstract: |
| In this paper, a method for shape optimization with discrete variables under dynamic stress and displacement constraints is presented. By using the quasi static method, the structure optimization problem under dynamic stress and displacement constraints are converted into one under static stress and displacement constraints. In the procedure of shape optimization, by utilizing structural analysis based on the first order Taylor series expansion with respect to the member forces and Mohr Formula, the nonlinear model are converted into linear one. The comprehensive algorithm for shape optimization of structure with discrete variables is used to obtain optimum solution. |
