Introduction The analysis of functionally graded materials has become a subject of increasing importance motivated by a number of potential benefits from the use of such novel materials in a wide range of modern technological practices.
As it is reported in the literature [6, 7], the graded materials are rarely isotropic because of the nature of techniques used in fabricating them.

A HISTORY OF THE FRACTOGRAPHY OF BRITTLE MATERIALS George D.
Quinn Ceramics Division, National Institute of Standards and Technology, Gaithersburg, MD 29899, USA george.quinn@nist.gov Keywords: Brittle Materials, Ceramics, Failure Analysis, Fractography, Fracture, Glasses, History, Microscopy Abstract: The evolution of the science of fractography of brittle materials initially was driven by failure analysis problems.
While the fractographers were documenting their findings, there were some important developments in materials science and mechanics fields.
One of the most influential brittle materials fractographers, Prof.
