This paper is concerned with the detection and characterization of impression damage in stiffened composite panels using elliptical triangulation system and higher frequency Lamb waves. Laminated composite resources, Utilized in quite a few aerospace and aircraft constructions, generally comprise several different concealed internal flaws which happen through manufacturing and processing of the material or even though the framework is subjected to company masses. In order to avoid rapid failure of structural components, a Distinctive interest was presented into the damage detection in complicated structures. A lot more particularly, structural wellness monitoring based upon the vibration of buildings is at the main focus of notice of many scientists in an effort to acquire very economical harm detection methods. In this way, couple nondestructive tactics based on measurement of Lamb waves had been formulated. On precisely the same solution is predicated the elliptical triangulation method presented With this paper.
