Fuzzy techniques for impact locating and magnitude estimating

This paper presents a methodology to locate impacts and estimate impact magnitude on smart composites. The methodology mainly comprises of impact monitoring, signal processing, feature processing and impact identification. In the methodology, four particular techniques are used: smart structures for impact detecting, cross-correlation for processing original impact signals, fuzzy clustering for feature selecting and adaptive neuro fuzzy inference system (ANFIS) for impact locating and magnitude estimating. The advantages by implementing these techniques are drawn in this study.
