Abedian and M. H. Ghiasi and B. Dehghan-Manshadi}, country = {}, institution = {}, abstract = {A stiffened laminated composite panel (1 m length × 0.5m width) was optimized for minimum weight and deflection under several constraints using genetic algorithm. Here, a significant study on the performance of a penalty function with two kinds of static and dynamic penalty factors was conducted. The results have shown that linear dynamic penalty factors are more effective than the static ones. Also, a specially combined linear-exponential function has shown to perform more effective than the previously mentioned penalty functions. This was then resulted in the less sensitivity of the GA to the amount of penalty factor.}, journal = {International Journal of Aerospace and Mechanical Engineering}, volume = {2}, number = {4}, year = {2008}, pages = {557 - 568}, ee = {https://publications.waset.org/pdf/5328}, url = {https://publications.waset.org/vol/16}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 16, 2008}, }
