of AZ91D tensile fractures Foundry A (a) and Foundry B (b) with corresponding SEM micrographs.
Samples were then evaluated via ring-on-ring, and fractography
was performed to determine critical flaw depths.

of fish-eye crack formation under bending-torsion fatigue," International Journal of Fatigue, vol.
These early investigations laid the foundations for the methodology, analytical tools and techniques such as fractography
and mechanical testing, which modern forensic investigators rely on.
His background extends to the areas of materials characterization, fractography
, metallography and mechanical testing.

The fatigue cracks observed during the fractography
analysis had the transgranullar character (Fig.
However, the most important advantage of chirp-coded TR-NEWS, which was used previously with another complex medium in the context of NDT , is the fact that the focusing of ultrasound is generated exactly at the position where laser surface velocity measurements are performed, and provides TR-NEWS with an advantage for localization of cracks and also the possibility of applying a surfacic stress, which could be combined to fractography
, and with ESAM-DORT  for their localization and imaging.
For instance, the knowledge of both analytical and topographical information can be of great interest when dealing with contacting surfaces (tribology), fractography
, surface functionalization, optimization of a fabrication process, etc.
Five chapters offer research and review studies on real-time fatigue damage monitoring via in situ ultrasonic sensing, multiscale approaches to fatigue crack growth from the debonding of particle/ductile-matrix interfaces, advances in the numerical modeling of fatigue crack closure using finite elements, textural fractography
of fatigue fractures, and a novel fractography
for investigation of the fatigue fracture process in materials.
