摘要: Online and offline monitoring of composite bolted joints under tensile load were investigated using piezoelectric transducers. The relationships between Lamb wave signals, pre-tightening force, the applied load, as well failure modes investigated. Results indicated that S0/A0 amplitudes decrease with increasing load. Relationships damage features mode built based on finite element (FE) simulation experimental results. possibility application wave-based structure health in joint-like structures was thus achieved.
