| Abstract | ||
| In this paper, damage detection for different types of defects (delamination, crack and hole) in the composite laminate plate and cylindrical shell be used to characterize the vibration behavior experimentally which used two types of load (plus and sine load) to find the frequency response. To this end, some plates and cylindrical shells are made using hand-lay-up process. Glass fiber is used as a reinforcement in the form of bidirectional fabric and general purpose polyester resin as matrix for the composite material of plates and cylindrical shells. From the results, the damage detection by using the Genetic algorithms is investigated. Also, these experiments are used to validate the results of free vibration obtained from the finite elements program. | ||
