摘要：

The resistance to local fracture of brittle materials is currently characterized by the value of edge toughness. An "instrumented micro-edge chipping" (IMEC) is proposed and tested. This test was carried out on various brittle materials: light krone glass LK-5, polycrystalline silicon Si, partially stabilized dioxide zirconium ceramic TS and tetragonal dioxide zirconium ceramic Y-TZP. IMEC test provides a closer correlation between the edge toughness Fr values at different values of the distance L between the test specimen edge and the indentation point than with the macro-EF test. Comparison of the macro-EF and IMEC tests for studied materials showed the almost identical trend in the ratio of the edge toughness values for all the studied materials. It was found that there is a significant time from the moment of crack formation to the full realization of the edge chip. The duration of the chip process is different for the studied materials.
