This paper presents a baseline-free, model-driven, statistical damage detection and imaging framework for guided waves measured from partial (i.e., non-dense) wavefield scans. Wavefield analysis is an effective non-contact technique for nondestructive evaluation. Yet, there are several limitations to practically implementing wavefield methods. These limitations include slow data acquisition and a lack of statistical reliability. Our approach addresses both of these challenges. We use sparse… CONTINUE READING
