Theoretical and experimental studies of oxide surface reactivity were combined to develop quantitative atomistic models for reactions which promote stress corrosion crack growth. These models address three basic processes influencing the structural reliability of ceramic materials: effects of mechanical strain and chemical environment on the kinetics of the crack tip bond rupture process, effect of surface reaction products on the structure and stress state at the crack tip, and chemical bonding mechanisms which can be used to heal fracture surfaces together. Silica glass was used in the studies.
