J0310201 Analysis of Water Vapor Pressure Dependence of threshold Energy Release Rate for Stress Corrosion Cracking in SiO_2 Base on Atomistic Model

Abstract

The threshold energy release rate for stress corrosion cracking, G_<th>, of SiO_2 in humid atmosphere is analyzed based on the atomistic simulation model of water molecule adsorption on the surface of SiO_2. The analyzed results of environmental partial water vapor pressure dependence of G_<th> coincide well with the experimental results.
