Abstract

This paper presents a concept for a built-in diagnostic system for detecting impact damage in in-service composite structures. The proposed system consists of two major diagnostic processes: passive sensing diagnosis (PSD) and active sensing diagnosis (ASD). The PSD utilizes the sensor measurements to determine the impact force and predict the location of the impact. The ASD generates diagnostic signals from the actuators to estimate the size of the impact damage resulting from the impact. In PSD, a computer code, `IDIMPACT,' has been developed for identifying impact force and location using distributed sensor measurements for both metallic and composite plates. For active sensing diagnosis, current work is focused on developing diagnostic methods based on the propagating waves. A key development for this work is to construct appropriate diagnostic waves for effectively detecting impact damage.
