Destructive identification approaches are no longer in favour ever since the existence of non-destructive evaluation approaches as they are accurate, rapid and cheap. Researchers are devoted in improving the accuracy, rate of convergence, and cost of such approaches which depend greatly on the types of vibrational experiments conducted and the types of forward and inverse methods used in numerical section. Therefore, this paper presents a review on the development of non-destructive vibrational evaluation approaches in identifying the elastic constants of composite plates, in experimental and numerical manners in order to enlighten researchers with the current trends of non-destructive vibrational approaches.
