PDC, acoustic radiation toughness test for PCBN or other high hardness or ultra-high hardness of the material,

摘要

Acoustic emission testing apparatus includes a pressure chamber, a rock sample, the acoustic sensor is one or more communicatively coupled to the rock sample. Pressure chamber, and a chamber of pressure possible second chamber of the pressure can be the first up to the pressure of the first, until the pressure in the second. Portion thereof with a first exposed to the pressure of the first portion of the second is to be exposed to a second pressure, rock sample is positioned in the pressure chamber. Pressure threshold pressurized to a predetermined period only held to the pressure threshold value, then the second pressure is decompressed. Acoustic sensor detects acoustic events of one or more generated in the rock sample. In certain exemplary embodiments, it is possible that the intensity of the acoustic event of one or more spatial locations, and determining the multiple of the travel direction. The system includes an acoustic emission testing device connected to the recorder. [Selection Figure 8
