A fratura de refratários é considerada sob o ponto de vista tradicional de resistência mecânica além da perspectiva da mecânica da fratura. Resistência mecânica e tenacidade à fratura são relacionadas por meio do tamanho dos agregados em re

The mirror region following the fracture initiation site is considered by applying fracture mechanics principles along with experimental observations of the crack velocity at the formation of the mirror mist boundary. Several issues regarding this cr

The Indentation Size Effect (ISE) in Fused Silica and Crystalline Quartz were measured by both Knoop and Vicker indenters and both exhibited a crossover for the different indenters at about the same indentation load. The crossover can be explained by

The crack patterns of glass which form when a propagating crack intersects a free surface are considered in terms of the (G,R) vs ∆C universal energy diagram for crack growth after Broek (1974) [1]. After briefly reviewing its derivation, the diagr

Thermal shock damage resistance in advanced refractories depends on the crack interactions with the microstructure. These energy dissipation mechanisms during crack propagation are not directly considered in the original classical thermal shock model

The topographical features which appear on the fracture surfaces of broken glass objects and the resulting crack patterns which develop are Nature’s documentation of the fracture event. They are considered after a brief discussion of glass strength

Evidence regarding a fracture event is absolutely and definitively recorded by Nature during the fracture process. That record is in the form of the general macrocrack pattern and the surface topological features of the newly formed fracture surface.

The Vickers indentation fracture toughness test, or VIF, is addressed by considering its origins and the numerous equations that have been applied along with the technique to estimate the fracture resistance, or the KIc of ceramics. Initiation and pr

The ZrC-ZrB2, ZrC-TiB2, and TiC-TiB2 metal diboride-metal carbide pseudo-binary eutectic systems have been successfully solidified directionally by means of the floating zone method. The first and third of these eutectics possess a morphology consist
