Determination of Bending Strength of Fine Ceramics Interface Four-point Bending Method

1 Scope

This standard specifies the terms and definitions, principles, and instruments for determining the method for determining the bending strength of the ceramic interface by using the four-point bending method at room temperature. Equipment, samples, tests, calculations and test reports. This standard is applicable to the determination of the bending strength of the interface between ceramics and ceramics, and ceramics and metals. The bonding interface of other materials can also be referred to use.

3 Terms and definitions

The following terms and definitions defined in GB/T 6569-2006 apply to this document. 3.1 Interface bending strength flexuralbondstrength The beam sample containing the butt interface reaches the maximum stress when the interface fractures under the action of bending load. 3.2 Four-pointflexure A loading form of the bending strength test, the sample is placed on two supporting rollers and passed through the two symmetrically distributed between the supporting rollers. Two upper roller bars are loaded simultaneously. Note. See Figure 1.The support roller and the upper pressure roller can adopt cylindrical roller shafts or cylindrical bearings. ......
