Abstract
DCB(double cantilever beam) specimen with double guiding grooves was selected and IDIC(increasing load-decreasing load-increasing load-constant load) method to measure continuously the curves relating da/dt (crack growth velocity) to K1(stress intensity factor) of SLS glass. The SCC characteristics of SLS glass immersed respectively in water, methanol, formamide were measured and analyzed. Their da/dt vs K1 curves show that the sensitivity of SLS glass to methanol is less than that for water but greater than that for formamide. It is deemed that the SCC sensitivity of SLS glass to environments is related to the asymmetry of lone-pair orbital and the activity of proton-donor bond.
