A Proposed Standard Practice for Fractographic Analysis of Monolithic Advanced Ceramics
The strength of many brittle ceramics reflects the flaws present in the material and the intrinsic fracture toughness. Interpretation of the strength results for monolithic, brittle advanced ceramics requires fractographic analysis whether mechanical testing has been done for quality control, materials development, or design purposes.
Progress is presented on an effort to develop a standard practice for fractographic analysis of laboratory strength specimens. The primary goal is to encourage fractography as a complement to mechanical testing. Procedures will be developed with regard to inspection techniques, sampling criteria and reporting practices.
