| Abstract: |
| Elastic properties of fiber reinforced composite laminates depend on fiber volume fraction and lay-up configuration (number of layers,ply angles and thicknesses).In this paper,the stiffness of fiber reinforced laminates with limited fiber volume fraction used is maximized by optimizing the lay-up and fiber distribution.In the formulation of this optimization problem,the design variables are the lamination parameters which are used to describe the layup of laminates and the characterization parameters which describe fiber volume fraction distribution in layers,the objective is the minimum compliance of laminates.Several design examples are shown for different rules of lay-up and fiber volume distribution. |
