Abstract
Time-resolved acoustic microscopy has been used to measure the 3-dimensional profile of short cracks (70-200 μm surface length). In order to establish this technique the depth of short cracks in transparent materials were determined. This allows a comparison between the acoustic and direct optical measurements. Subsequently the depth of cracks and the growth of short fatigue cracks in Al-alloy were measured
