Determination of Elastic Constants Required for Application of Fracture Mechanics to Ceramics. is the energy release rate, K. is the stress intensity factor, and E is Young’s modulus. For an elastically orthotropic body the sajne result holds provided 1/E is replaced by (s.s./2).. where the s. are the single crystal elastic compliances. These equations may be used to

Origin and Detection of Microflaws in Glassf the product, and are clearly not relevant to a conference on fracture mechanics. Others, such as an irregular wall thickness in a bottle, may affect the fracture behavior, but such obvious and macroscopic defects are not to be the concern of this review. We shall confine our attention to more-subt

Microstructural Aspects of Acoustic Emission Generation in Ceramicsics prior to failure and to see if these signals have any characteristic features which can be used to determine the microscopic process taking place within the material. In the first section, the techniques used and the materials studied are outlined. Section II then describes the characteristic fe

Observation of Crack Propagation in Polycrystalline Ceramics and Its Relationship to Acoustic Emissichievement of this goal has been thwarted by the brittle nature of ceramics which causes failure as a consequence of stress concentrations arising at crack tips or other flaws. The nature of the ‘critical flaw’ which precipitates failure is of considerable interest to both fabricators of ceramics an

The Initiation and Propagation of Hertzian Ring Cracksndition under which Hertzian ring cracks initiate on glass surfaces. The case of cracking produced by a flat cylindrical punch is also considered and is compared with that due to a sphere. It is shown that ring cracking data obtained with a punch, or less conveniently with a sphere, may be used to d

The Interaction Between Inclusions and Cracksnd distribution of flaws or imperfections in the material. In studying the “bulk strength” and other bulk properties of the composite it is generally assumed that these flaws are randomly distributed throughout the material and hence the medium is statistically homogeneous. Therefore, in this type o
