| Abstract |
A design optimization procedure is presented for an I-section composite beam using micro genetic algorithm. An analytical model for a thin-walled composite beam is given. The objective functions and constraints are given in the form of beam stiffnesses. Design variables are given as fiber directions in the beam walls. Numerical results show that the present Micro Genetic Algorithm(μ-GA) gives excellent performance in design optimization of I-section composite beams. |
