    Abstract

    The use of pulsed-laser holography with impact loading in nondestructive testing was investigated. Induced flaws in the material were detected by holographic, nondestructive testing (HNDT) approach where they influenced the local mechanical characteristics and caused an aberration in the deformation when mechanically loaded. The present defects were debonds of the forward surface. The obtained results showed that the HNDT method, which does not need vibration isolation, is well-suited for nondestructive testing. Moreover, the method proved to be reliable and accurate. The holograms were determined to be insensitive to changes in loading points and sample prestressing.
