Introduction
The thermoelastic stress measurement method uses the thermoelastic effect of materials to measure the surface stress distribution of materials and structures: It is a "comprehensive
Field "non-contact" measurement technology: Unlike traditional technologies such as the strain gauge method, the unique advantage of this method is that it can easily measure the entire specimen
The surface stress distribution (Δ(σ1 σ2)) is imaged (see ISO 10878):
With the development of thermal imaging technology, the industrial application of thermoelastic stress measurement methods is becoming more and more widespread: Application of thermoelastic stress measurement method
The effectiveness depends on the correct use of the method: This document has been developed to establish the general principles of thermoelastic stress measurement methods to facilitate
This method is correctly and effectively applied to non-destructive testing in various industrial fields such as automobiles, aerospace, electronic instruments, medical equipment, and industrial materials:
Nondestructive testing infrared thermography to detect thermoelastic stress
General rules for measurement methods
1 Scope
This document establishes the general principles for thermoelastic stress measurement methods in infrared thermal imaging testing in the field of industrial non-destructive testing:

3 Terms and definitions
The terms and definitions defined in ISO 10878 apply to this document:
4 Infrared thermal imaging inspection personnel
Personnel performing infrared thermography testing (TT) including thermoelastic stress measurements should comply with the following requirements:
a) TT personnel should have sufficient inspection knowledge, including thermal imaging inspection and testing in accordance with ISO 9712 and ISO /T S25107
Basic knowledge of heat transfer engineering;
b) The vision and color discrimination ability of TT personnel should comply with the requirements of ISO 9712:
5 Detection environment
5:1 Testing equipment environment
Conduct inspections in an environment where the temperature, humidity and air pressure are suitable for the operation of inspection equipment (including thermal imaging cameras that comply with ISO 10880):
Measurement: Avoid condensation on the surface of the object being measured:
In order to avoid image blur due to field of view jitter, try to avoid vibration of the infrared thermal imaging camera: When the vibration period of the infrared thermal imaging camera is different from the measured
When the object's loading cycle is synchronized, the impact can be reduced through position correction technology:
