“…Both the surface scratches and pits caused the structural degradation and damage of the glass plates. As suggested by Yang [23] in examining the indentation behavior of ground ULE™ glass and Swab et al [24] in studying the effect of surface scratches on the bending strength of soda-lime silicate and borosilicate glass with a large scratch load, the surface scratches and pits led to the decrease of the apparent surface strength and modulus.…”

“…The pattern of crack formation during scratching of chemically toughened glass was found to differ from heat treated (fully toughened or heat strengthened) glass in that lateral cracks preceded the formation of radial/median cracks in the former (Gross 2012). Unsurprisingly, strength reductions were reported for heat treated and annealed glass after scratching; scratched heat treated glass was stronger than scratched annealed glass indicating that the depth of the flaws induced were smaller than the case depth (Swab et al 2013).…”

Glass is known for its excellent durability, but the strength of glass is very sensitive to the characteristics of its surface, which is known to accumulate damage during its service life. There is however, a lack of strength data on weathered or aged glass, particularly on thermally or chemically treated glass. In this study a carefully calibrated sand trickling test is used to produce surface damage equivalent to erosive action of 20 years of natural weathering on different types of glass: soda-lime-silica annealed, soda-limesilica fully toughened and aluminosilicate chemically toughened. The soda-lime-silica glass specimens are tested destructively in their as-received and artificially aged form in a conventional coaxial double ring setup, while the alumino-silicate chemically toughened specimens are tested in an improved coaxial double ring set-up. Fractography is subsequently used to identify and measure the critical flaw size on each specimen. The strength data are analysed statistically and the design strengths for each glass type are obtained. It is found that all glasses suffer a loss in strength after artificial ageing, with fully toughened glass providing the best post-aged performance. It was also found that Electronic supplementary material The online version of this article

“…However, most equipment can only obtain information such as width and location (Wiederhorn, 1969;Shand, 1965). As the strength of glass material is determined by both the shape and the depth of surface damage (Glaesemann et al, 1987), 3D characterization herein has drawn the attention of researchers (Swab et al, 2013).…”

Glass material has been widely used in modern architecture. Scratch-induced surface damage of aged monolithic glass panel leads to the strength degradation of material and thus threatens the glass safety. Therefore, in order to accurately evaluate the strength of aged glass elements, it is crucial to extract key damage features including the damage location and depth in a precise way. This study aims to develop a non-contact stage-wise scanning method to extract 3D damage characteristics on glass surface, which can further facilitate the investigation into the associated influences on the flexural strength of glass. Coaxial double ring tests on annealed glass specimens under various magnitudes of applied loads were performed, which aimed to explore the influence of the surface damage on the flexural strength. Monocular microscope equipped with an industrial camera was used to detect damage area throughout the glass panel in the first stage rapidly. It was then followed by a chromatic confocal scanner to precisely measure the damage depth within local damage area. The results via confocal microscope scanning were considered as the reference values. It shows that the proposed method can be a potentially alternative solution instead of confocal microscope for damage quantification.
