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
