Indentation Fatigue and In Situ Inspection of Damage Evolution for Glass

Abstract:

Article Preview

Initiation and propagation of Hertz crack in glass was investigated by combining sphere indentation test and optical microscope under a transparent testing platform. Thus, the process of the crack growth in glass and the critical indentation load and contact crack radius could be determined conveniently. Indentation fatigue tests were carried out to understand the contact damage resistance, the fatigue cycle number for cracking increase with decrease of the fatigue load. This simple testing method is demonstrated convenient and available for calculating the surface local strength of glass in situ via measurements of the critical load and contact crack size.
