Abstract

Mechanical testing and cyclic fatigue testing belong to the important material examinations. Standard fatigue testing is mostly time-consuming and needs a number of identical samples that makes the testing expensive. Infrared thermography as a noncontact method of temperature measurement is used in many industrial applications. As the mechanical energy is changed to thermal energy during the cyclic loading, the infrared thermography can be used for fatigue testing. Most of the research regarding fatigue limit evaluation by infrared thermography has been focused on a measured data post-processing. An online evaluation of infrared thermography measurement during a sample cyclic loading is introduced in this contribution.
