Abstract
Mechanical structures during their functional operations may be vulnerable to damage and therefore cannot be guaranteed definite fault free operational and successful exploitation. This paper presents the modal analysis for the use of PZT actuator in repair of cracked cantilever aluminium beam by using Finite Element Analysis (Ansys) software. Cantilever beam vibrational response is analysed and the numerical results of undamaged beam, damaged beam and damaged beam with piezoelectric material patch at different locations compared to different scenarios of damage presence in structure, by location and depth of single transversal notch. Technique is based on idea, if notch appears in mechanical structure which leads to change in physical properties leading to the drop in natural frequency. By using the piezoelectric patch the dropped natural frequency are tried to be restored to the Natural frequency of healthy beam.
