Trial Study on Methods of Damage Extent Identification Based on Wavelet Transform of Strain Signal

Abstract:

Wavelet transform of strain signal can be used in the damage relative damage extent identification. The proposed method is validated by trial on a simply supported steel beam. And meanwhile the relative damage extent can be identified by drawing the curve of the maximum modulus of the wavelet coefficient and damage extent.
