The effect of residual contact stresses on the dynamic fatigue behavior of indentation flaws was analyzed using an exponential‐law crack velocity function based on stress corrosion theory. Analysis of strength data from Vickers‐indented soda‐lime glass specimens in water showed that the contact residual stress can be properly accounted for and that the exponential‐law fatigue parameters can be straightforwardly obtained.
