UNCERTAINTY BASED OPTIMIZATION OF COMPOSITE LAMINATE SUBJECT TO FREQUENCY CONSTRAINTS

摘要：

This paper investigates the optimization of composite laminate subject to frequency constraints, while accounting for the uncertainties in material properties. The approach is based on the combined use of structural reliability analysis, composite mechanics and genetic algorithm. The Response Surface Method(RSM) is applied in the probabilistic reliability evaluation. In the uncertainty-based optimization of composite laminate, the mass of the laminate is maximized in terms of the ply number and fiber orientations, subject to frequency constraint. Numerical examples are conducted, the difference between the determined optimization and uncertainty-based optimization is clarified.
