Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
The standard instead of GB/T 7314-2005 "metal materials at room temperature compression test method", compared with GB/T 7314-2005 main technology
The content changes as follows.
--- modified the standard English name;
--- Added GB/T 8653 and GB/T 10623 two normative references (see Chapter 2);
- modified terms and definitions (see Chapter 3);
--- modified the principle of the statement (see Chapter 4);
--- modify the sample of the legend, unified use of the new roughness labeling method (see Figure 1, Figure 2, Figure 3, Figure 4);
- modified test conditions (see Chapter 8);
- the numerical correction interval of the performance determination results has been modified (see Chapter 10);
- the removal of the uncertainty of the performance determination results (see Chapter 11 of.2005);
- modified test results (see Chapter 11, Chapter 12 of.2005);
- modified part of the test report (see Chapter 12, Chapter 13 of.2005);
- Appendix A has been deleted (see Appendix A of.2005).

3 terms and definitions
The following definitions and definitions as defined in GB/T 10623 apply to this document.
3.1
Buckling buckling
In addition to compression failure caused by compression, the following methods may also occur compression failure.
a) due to non-axial force caused by the cylindrical specimen in its length of the elastic instability;
b) Inelastic instability of the column specimen at its full length;
c) elastic or inelastic local instability on small areas of plate specimens;
d) Twist or torsion failure occurs when the cross section of the specimen is rotated about its longitudinal axis. These types of failures are collectively referred to as buckling.
3.2
One-way compression singlecompression
When the specimen is subjected to axial compression, the effect of bending is negligible, and the stress in the gauge is evenly distributed, and no buckling occurs during the test.
3.3
Sample original gauge gaugeoriginalgaugelength
L0
To measure the original length of the part of the specimen deformation, the length should not be less than the width or diameter.
3.4
Actual compression force realcompressionforce
The force acting in the direction of the specimen axis during the compression process; the plate-like specimen, which is clamped in the restraint device, is the midpoint of the gauge
