Abstract
The free vibration and static stability behaviour of a rectangular plate with localized zones of damage is studied using a finite element analysis. The influence of parameters such as size of damage, extent of damage, position of damage, plate boundary conditions and aspect ratio of the plate on vibration and instability behaviour are discussed. It is observed that the presence of damage has a marked effect on the static buckling load and natural frequency of the plate. A flaw in the plate near its centre usually renders the natural frequency and buckling load of the plate to a minimum value.
