A Rapid Damage Assessment Method Based on Association Rules of Feature Factors

The rapid assessment of structural damage under finite conditions is of great significance for ensuring structural safety. A rapid damage assessment method based on association rules of feature factors is studied. The entire monitoring area into several small monitoring unit, using active Lamb wave monitoring method, in each monitoring unit for damage characteristic factor. The characteristic factors of the same monitoring unit and adjacent monitoring units are correlated by the association rules of the characteristic factors. So as to realize the rapid assessment and detection of damage occurrence and expansion. The results are verified by experiments on typical composite structure specimens. The experimental results show that the method can realize the rapid monitoring and expansion estimation of structural damage, and intuitively display the location, scope and development trend of damage, and has a certain application prospect.
