Identification of multiple damage in beams based on robust curvature mode shapes
We discuss the susceptibility of traditional curvature mode shape to noise. We propose a TEO-WT curvature mode shape for multiple damage detection in beams. TEO-WT curvature mode shape is demonstrated by detecting multiple damage in beams. TEO-WT curvature mode shape is experimentally validated by laser measurement.
