N2 - In previous quasi-static spherical indentation testing of soda-lime-silicate (SLS) glass, it was conclusively and repeatedly shown that lowering the elastic modulus of the ball material resulted in the causation of ring crack initiation at lower compressive forces. This was due to differences of elastic property mismatches between indenter ball and target glass and the changes in traction friction caused by those mismatches. Given that, interest existed in the present study to examine if this effect was also operative during the ball impact of SLS glass at low velocities (< 30 m/s or 65 mph). Borosilicate glass, SLS glass, Si3N4, Al2O 3, and steel balls were used for the impact testing, spanning a range of elastic moduli from 63 to 375 GPa. It was observed that the onset of impact damage in the SLS tiles was not solely a function of the ball's kinetic energy at this velocity range, and that the effects of elastic modulus mismatch of the ball and SLS glass target could be contributing to the target response too.
