Scaling exponents for fracture surfaces in opal glass

Strength Enhancement of Soda-Lime Silica Glass Using Ionexchange Process

“…(6e)-(6f), which corresponds to the non-treated and treated specimens, respectively. In both cases the roughness exponent has values consistent with the claimed universal value ζ ∼ 0.8 (Chavez and Garza, 2010). This implies that the ionic exchange treatment does not modify the exponent characterizing the selfaffine regime.…”
