Abstract
This paper studies on the optimal stacking sequence for vibration of FRP laminated circular cylindrical shells. For this purpose, the frequency equation for a simply-supported shell is derived based on Flugge-type classical lamination theory, and then two types of optimization problems for the shell are formulated by employing continuous design variables and by discrete design variables, respectively. In optimization, two types of genetic algorithms are also employed to solve these optimization problems. Optimal design solutions are obtained for the laminated shells with different stacking sequence from numerical calculations, and the maximization for fundamental frequency of the shell is also studied by comparing with numerical results obtained.
