摘要：

The edge chipping of borosilicate glass by the low velocity impact of freely falling steel and ceramic balls was investigated experimentally. The maximum impact forces were recorded using a force sensor, and comparisons were made between edge chipping by impact and quasi-static loading. In general, edge chipping by impact loading required lower forces than by quasi-static loading. This was attributed to the reduced constraint in the impact tests which created a bending moment at crack tips causing cracks to deviate toward the edge and form chips. (C) 2011 Elsevier Ltd.
