N2 - Fracture toughness test and Modified Small Punch(MSP) test by use of Acoustic Emission(AE) Technique were performed on Y2O3 stabilized ZrO2, 3mol% Y2O3 - ZrO2 (PSZ)/SUS composite materials, and Macor which is a machinable ceramics. MSP testing method(miniaturized test technique) was developed to determine fracture strength, and fracture strain with high accuracy and good reproducibility, where AE monitoring was also made. From these results, AE characteristics of various materials were compared, and microscopic fracture mechanism was discussed on the basis of the AE results. Furthermore, the AE for stress induced transformation in 3, 4 mol% Y2O3 - ZrO2 were also examined.
