“…The value of the mirror constant is shown to also be approximately 1.9 MPa m 1/2 . For example, these results are in Mecholsky et al . A more recent demonstration of this independence of thickness is on page 105 (Fig.…”

“…If one looks at the fracture surface of a glass fiber, one finds that the mirror constants associated with fracture are identical to those for the bulk glass, suggesting that at more rapid crack velocities where mirror formation occurs, the growth mechanisms are the same. The major questions arise with respect to delayed failure in fibers.…”

This paper presents a summary of brittle fracture in silicate glasses. In it is discussed our current knowledge of the fracture mechanisms, what studies are ongoing, and what still remains unknown. The paper presents a historical perspective of the research into glass fracture including an annotated bibliography of key publications. Several key points include the susceptibility of silicate glasses to environmentally enhanced crack growth, the quantitative nature of the markings left on the fracture surface by a growing crack, the issue of crack arrest at low stresses, and recent work on the atomistic modeling of the fracture process. The paper concludes with a summary of both what we know, and what is yet to be learned about the important topic of glass fracture.

“…The fracture surface of a failed glass fibres shows three characteristic regions: 1 the mirror zone, a smooth planar surface with a mirror-like finish; 2 the mist region, an area where small radial ridges can be seen; 3 the hackle, a region showing larger radial ridges [15J [16] [17]. The fracture surface is evident in specimens tested in air and those that have undergone stress corrosion.…”

Pultruded glass fibre reinforced plastics (or GRP) rod is being increasingly used in the area of cable design, used for strength members in optical fibre cables. The possibility of failure by the process of stress corrosion has resulted in the need to determine the reliability of the dielectric cables when in service. The viability of life predictions being made from the study of stress corrosion fracture surfaces is investigated. The production of static fatigue data for composite materials is needed to enable any accurate predictions to be made.
