摘要

The acoustic emission method was employed for investigation of fracture process of the 95% alumina ceramic and zirconia toughened alumina (ZTA) with a 15% volume fraction of tetragonal zirconia in the Brazilian split test. Geiger location algorithm was used for location analysis. The results showed that calculated AE locations by Geiger algorithm and ceramics failure process were consistent and the location results could reflect the process of damage. In the initial stage the quantity of AE events is very little, and AE events significantly increase after the initial crack formation. In the unstable stage AE events can hardly be captured due to the sampling frequency constraint. The toughening effect of ZTA can be analyzed through acoustic emission waves, hits, and signal amplitudes.
