In situ damage detection in frame structures through coupled response measurements

Prediction and Direct Measurement of Scattered Plate-Wave Fields Using S0 to A0 Mode Conversion at Non-Symmetric Circular Inhomogeneities

“…This may be achieved through illumination of the defect by a, to the detector invisible, wave mode that mode converts to a wave mode of detectable polarization (mode conversion from SO to AO in this case). Mode conversion occurs at non-symmetric defects, which are the most likely type of defect to be encountered in practice and can be used as sensitive damage indicator [4].…”

Identification of multiple cracks in beams under bending

“…Liu et al [26,27] detect a circumferential crack in a hollow section beam analytically and then experimentally. The coupled response property due to the crack is used to identify the crack in a frame structure.…”
