Compressive Microfracture and Indentation Damage in Al2O3

  • Chapter
Flaws and Testing

Part of the book series: Fracture Mechanics of Ceramics ((FMOC,volume 3))

Abstract

During the impact of ceramics by small hard particles, indentation damage is caused, which can lead to erosion and/or strength degradation of the ceramic. It is suspected that certain types of indentation-induced flaws may be generated by the compressive fields known to be associated with such loading. Accordingly, a research program was carried out to assess the mechanisms of damage in a strong ceramic subject to compressive loading, and to determine, if possible, the relevancy of such mechanisms to indentation damage.
