摘要：

The paper presents the defect detection in plates considering the influence of dynamic characteristics, especially with regard to the vibration modes. The aim if this work is to detect the localization of a defect provided that damage exists in the considered plate structure. The Kirchhoff plate bending is described and solved by the Boundary Element Method (BEM). Plates have rectangular shape and different boundary conditions. The analysis of a structural response is carried out with the use of signal processing tool namely Discrete Wavelet Transformation (DWT). Defects in plates are introduced as slots near the plate boundary.
