A simple measurement technique to evaluate micro cracks in a solid PMMA specimen is reported. Taking advantages of a two layered transducer composed of PVDF and ceramic transducers, and laser induced pulse elastic waves, we have tried to obtain three dimensional images of the crack. By using the high amplitudes and low frequency strong vibration by the ceramic transducer, we have obtained interesting images, which seem to show the position of cracks tips. In this report, a 3-D mapping of the crack tips was tried. |
