Modal testing has become commonplace in many industries today as a research and development tool.
In this capacity, it is used primarily during product prototype development and for vibration problem in general .
Many types of structural or parts faults will cause changes in the measured dynamic response of a structure.
These changes will, in turn , cause change in the structure’s modal parameter .
The purpose of the present work is to propose an improved damage detection and location based on the measurement of modal parameter (natural frequency and mode shape ) before and after faults , which they have varying extents, for three different sizes of Aluminum casing plates.
This local damage can be translated into or characterization as a reduction of the local stiffness which , simulated in the presented numerical models using software package.
After measured natural frequency , if a change is detected a statistical method is used to make the best match between the measured changes in frequencies and the family of the theoretical predictions.
This predicts the most likely defect location .
Analytical results are also used to check numerical results , which showed a good agreement with it , standard Aluminum plates were also investigated in this work .
It results were compared with casting results for two boundary conditions .
Also , the defect location charts that plotted with the support of deriving stiffness sensitivity equation showed a good agreement between the predicted defect site and the actual defect location for most of the study cases .
