Soda‐lime‐silica glass was fractured under combined mode I and mode II loading from flaws produced by hardness indentations. Critical stress intensities calculated from K 1 and K 11 combined using four analyses, are compared to K IC measured by a fracture mechanics technique and to values of K IC determined by measuring fracture‐mirror size. The comparison showed that K IC calculated using a noncoplanar strain‐energy release‐rate analysis gave the best agreement with values obtained by fracture mechanics techniques over the widest range of crack orientations. K IC calculated from mirror sizes was constant regardless of the orientation of the original flaw.
