Determination method of tensile strength of ceramic materials for daily use

1 Scope

This document describes a method for the determination of the tensile strength at room temperature of sintered samples of ceramic materials for daily use. This document is applicable to the detection of ceramic materials for daily use.

2 Normative references

The contents of the following documents constitute the essential provisions of this document through normative references in the text. Among them, dated references For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document. GB/T 5000 Terminology of Ceramics for Daily Use

3 Terms and Definitions

The following terms and definitions defined in GB/T 5000 apply to this document. 3.1 At room temperature, the ability of a material to resist tensile damage is the maximum tensile stress that a sample can withstand on a unit area.

4 principles

According to the theory of elasticity, two concentrated loads uniformly distributed along the length of the sample are applied in the diameter direction of the cylindrical sample in opposite directions. On the radial plane bearing the load, there is a uniform tensile stress separated from the left and right perpendicular to the plane. With the gradual increase of this stress, the final Cause tensile fracture (see Figure 1).
