Abstract

Non-destructive testing has been implemented in many industries to ensure structural safety and reliability by detecting defects. In this study, Lamb waves are used for early damage detection and characterization. The aim of this research work is to develop a methodology for damage characterization (detection, localization, severity, and life estimation). Different problems associate with Lamb waves propagation as their dispersive behavior, and the effect of varying temperature on the amplitude and arrival time of the wave. Current study focuses on investigating the multistage damage detection method based on Lamb waves. It uses a network of transducers to improve damage detection and localization. It is aimed to validate the present technique by ellipse method to improve damage localization of the previously detected damages. To model the first stage of the technique, numerical simulations were performed on an 800x800x1.293 mm aluminum plate, using FE software ABAQUS explicit. Obtained signals from the simulation can detect s the presence of damage by comparing the baseline signal with damaged signals. The corresponding delays have been validated and compared with those of literature to improve the estimation of damage position.
