Imaging of planar defects with LSAFT

Kari Lahdenperä

    Research output: Book/ReportReport


    In 1985 three specimens with internal fatigue cracks supplied by VTT were imaged by LSAFT in Saarbrucken by IzfP. The results were compared with the results from earlier measurements of the specimens in 1980 by the surface wave method. As a rule the new results were in a good agreement with the earlier results on crack height and position. Also the main principles of SAFT are described as well as the manufacturing of the specimens used.
