“…The resistance against the formation of median and radial cracks can be approximated by a pragmatic Vickers indentation test. In this test, the glass specimen is indented with stepwise increasing loads until the appearance of cracks can be observed at the corners of the residual hardness imprint [70]. In the current study, the sodium-borosilicate glasses were indented with loads ranging from~50 mN up to~20 N and the amounts of radial cracks emanating from the corners of the indent were counted using an optical microscope.…”

We provide a comprehensive description of the defect tolerance of sodium-borosilicate glasses upon sharp contact loading. This is motivated by the key role which is taken by this particular glass system in a wide variety of applications, ranging from electronic substrates, display covers and substrates for biomedical imaging and sensing to, e.g., radioactive waste vitrification. The present report covers the mechanical properties of glasses in the Na 2 O-B 2 O 3 -SiO 2 ternary over the broad range of compositions from pure SiO 2 to binary sodium-borates, and crossing the regions of various commercially relevant specialty borosilicate glasses, such as the multi-component Duran-, Pyrex-and BK7-type compositions and typical soda-lime silicate glasses, which are also included in this study. In terms of structure, the considered glasses may be separated into two groups, that is, one series which contains only bridging oxygen atoms, and another series which is designed with an increasing number of nonbridging oxygen ions. Elastic moduli, Poisson ratio, hardness as well as creep and crack resistance were evaluated, as well as the contribution of densification to the overall amount of indentation deformation. Correlations between the mechanical properties and structural characteristics of near-and mid-range order are discussed, from which we obtain a mechanistic view at the molecular reactions which govern the overall deformation reaction and, ultimately, contact cracking.

“…Fracture surface energy of various glasses estimated from their elastic modulus. [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] impact energy, the particle size differs in the particle size distribution. Therefore, the glass size reduction can only be decided by their brittleness in the particle size distribution.…”

“…Indeed, chemical strengthening is a mature technique; however, there is still plenty of room for the improvement of crack resistance since knowledge on the relationship between crack resistance and glass structure is limited, even though many studies have been conducted [7][8][9][10][11][12][13] to obtain higher-crack-resistant glass.…”
