Abstract

The paper presents the problem of damage detection basing on the phenomenon of reflection and diffraction of waves at damage boundaries. Elastic waves in plate structures are considered. Damage is modeled as stiffness reduction at a small domain. One-dimensional discrete signals, representing the velocity or acceleration measured at specified time and plate sections are analyzed using wavelet transform. (© 2004 WILEY-VCH Verlag GmbH & Co.
