Abstract

Wave field imaging method has been an effective visualization method in damage detection since the past decades. However, existing imaging methods still have problems when applied to complicated composite structures. In this paper, an improved adjacent wave subtraction (AWS) method is proposed to visualize damage in stiffened composite structures. A robust time window is illustrated to enhance the anomalous wave signals and improve the imaging results. The method is proved to be effective in stiffened composite panels with numerical simulations and experiments.
