• VIBRATION PARAMETERS FOR DAMAGE DETECTION IN STRUCTURES

  Publication

  • M. Palacz
  • M. Krawczuk

  - JOURNAL OF SOUND AND VIBRATION - Year 2002

  The aim of this paper is to examine how damage indicators are sensitive to changing number of frequencies and mode shapes and also to number and location of measurement points. The influence of measurement errors was also analyzed for all cases. For the analysis, those damage indicators are chosen which use changes in such modal parameters as natural frequencies and mode shapes and also differences between the curvatures of the damaged...

  - Year 2007

  Wykrywanie i lokalizacja uszkodzeń w konstrukcjach inżynierskich są przedmiotem intensyw-nych badań z powodu ich praktycznego znaczenia. Niezwykle istotne jest wczesne wykrycie uszko-dzeń w konstrukcjach inżynierskich o szczególnym znaczeniu, ponieważ ich propagacja może do-prowadzić do katastrofy budowlanej. Stosunkowo nową dziedziną badań w wykrywaniu zniszczeń jest zastosowanie analizy falkowej. Metoda ta bazuje na postaciach...

• Damage detection in plates based on Lamb wavefront shape reconstruction

  Publication

  • B. Zima

  - MEASUREMENT - Year 2021

  Many of the current studies in the area of damage detection using elastic wave propagation are based on deploying sensor networks with a large number of piezoelectric transducers to detect small-size cracks. A major limitation of these studies is that cracks are usually larger and have different shapes in real cases. Moreover, using a large number of sensing nodes for damage detection is both costly and computationally intensive....
