Abstract
This paper discusses a new method for detection of crack damage in plate structures based on direct application of with a 3D scanning laser vibrometer. The recent advances in scanning laser technology now allow a very accurate measurement of the displacement field, which in the case of undamaged structure must satisfy the fundamental equations of continuum mechanics everywhere. A violation of these equations at specific locations indicates the presence of the damage, which can be detected and sized by utilising a defect search algorithm.
