Inert failure strains of sodium aluminosilicate glass fibers

Inert failure strain studies of sodium silicate glass fibers

“…It appears that the Ôhigh silicaÕ glasses with more cross-linked structures respond to the applied stress in a different way than the glasses with structures that possess significant numbers of non-bridging oxygens. Similar conclusions were drawn in our recent study of the inert failure strains of Na-aluminosilicate glasses [19].…”

Intrinsic failure and non-linear elastic behavior of glasses

“…The measured TPB failure strains at 77 K for silica fibers are about 18% [12]. Recently, using TPB, failure strains as high as 23.5% are reported for sodium silicate glass fibers [13], 21% for sodium alumino-silicate fibers [14], and 13% for E-glass fibers [15]. These high failure strain values also correspond to intrinsic failure for the same reasons mentioned earlier for failure strengths in pure tension.…”

Fracture‐ and Indentation‐Induced Structural Changes of Sodium Borosilicate Glasses

“…[12][13][14][15] A fiber sample bent in a U-shape between two face-plates was immersed in liquid nitrogen (77 K) and one of the faceplates was driven at a constant rate of 2000 lm/s until the fiber failed. A lab-made TPB tester was prepared according to previous studies.…”

“…In this study, two-point bending (TPB) technique [11][12][13][14][15] is employed to apply a high tensile stress to glass fibers, because this technique enables us to measure intrinsic failure strains which are over 15% for silica and over 20% for some binary sodium silicate glasses.
