Room temperature isobiaxial bending of fine ceramics Strength test method double loop method

1 Scope

This document specifies a test method for the biaxial bending strength of fine ceramics using the double-ring method at room temperature. This document is applicable to the determination of biaxial bending strength of single-phase ceramic materials with an average grain size less than 100 μm. This document also applies The average grain size (or length) of each phase is less than 100 μm, and biaxial bending of composite phase ceramics reinforced by particles, whiskers and/or discontinuous fibers Determination of bending strength.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 σrr The test sample is subjected to linear elastic and other biaxial bending loads through the double-loop method, and the maximum stress at which the sample breaks and fails.

4 Principles

A disk-shaped sample of equal thickness is placed between two concentric rings of different diameters, and a load perpendicular to the plane of the sample is applied. The equibiaxial bending strength of the sample was calculated based on the sample fracture load, sample geometry, and Poisson's ratio of the sample material.

5 Meaning and use

This document is used for materials development and characterization, quality control, and materials design. The material being tested is elastically uniform and isotropic, and has linear Stress-strain properties. The strength of the disc-shaped sample was calculated based on its linear elastic bending properties. The strength test results are determined by the microstructure of the material, the sample It is determined by various factors such as product surface processing procedures, sample size and shape, loading rate and environmental relative humidity. As described in this document, the For many purposes, the results of a strength test can be described in terms of mean and standard deviation. The test results can be compiled in accordance with GB/T 40005 Design analysis to meet material design. ......
