The microindentation technique was used to determine the interfacial fracture energy of epoxy coatings on soda-lime glass substrates. An analytical model was developed for calculating fracture energy based on indenter load versus debond crack size measurements. Finite-element analysis was used to determine the relative amounts of opening and shear loadings at the debond crack tip. The calculated fracture energies are compared to values determined by the double-cantilever-beam technique and the four-point flexure-beam technique.

Fatigue of silicate glasses was studied using both static and dynamic tests. Static fatigue data for acid‐etched soda‐lime silicate glass determined at 74°F in 50 and 100% rh can be represented by a single universal fatigue curve (UFC). The UFC for acid‐etched glass does not lie on the UFC of Mould and Southwick, which was determined for abraded soda‐lime silicate glass; the acid‐etched glass was less susceptible to static fatigue. The susceptibility of acid‐etched soda‐lime silicate glass to static fatigue differed little from that of pristine E‐glass and fused SiO2 fibers. Dynamic fatigue data for soda‐lime, E, borosilicate, and fused quartz glasses agreed well qualitatively and quantitatively with fundamental crack velocity data for these glasses; the dynamic fatigue theory of Charles was used in the comparison. The theoretical implications of these results are discussed.
