Figure 10

Photographs of impact breakage process recorded by high-speed camera. (a) Sample code is SQ89, mass is 259 g, sphericity is 0.64, specific breakage energy is 169 J/kg, and fragment number is three. (b) Sample code is S17, mass is 265 g, sphericity is 0.66, specific breakage energy is 248.7 J/kg, and fragment number is three. (c) Sample code is SQ87, mass is 256 g, sphericity is 0.74, specific breakage energy is 305.1 J/kg, and fragment number is three. (d) Sample code is S16, mass is 232 g, sphericity is 0.579, specific breakage energy is 128.4 J/kg, and fragment number is four. (e) Sample code is SQ90, mass is 260 g, sphericity is 0.74, specific breakage energy is 223.7 J/kg, and fragment number is five.
