### Impact work index prediction from continuum damage model of

Bond 1947 defined the impact energy per unit of thickness CB by dividing the impact energy by the thickness of each particle w so that 1 C B 117 1 cos / w where is the angle w is given in mm and CB in J/mm. From this and the material specific gravity s in g/cm 3 Bond proposed to estimate the crushing work index using the
