In this study, the edge shape effect on the impact and bending strength of glass sheet was carefully investigated by using edgeimpact test (EIT) and 4-point bending (4PB) test. The Weibull data obtained from EIT showed that round shape was moreresistance to impact test regardless of the tilted stage angle and the strength values were in the order of round shape, bevelshape, and cut shape. When it comes to the bending strength, it was insensitive to the edge shape unlike the impact strength. Fracture analysis proved that the origins were located around the grinned surface and the breakage behavior of round shapewas different those of bevel and cut shape. The mirror strength was calculated by the means of measuring the mirror radius,and the relationship compared to the tensile stress was discussed in detail.
