Fatigue Limit Evaluation Using Thermographic Measurementduring Cyclic Loading - 1D and 2D method
Original language description
Testing of material fatigue properties belongs to important material examinations. A standard fatigue measurement is mostly a time-consuming and expensive experiment, among others due to a number of samples needed. Infrared thermography is a method for a noncontact temperature measurement. Thermographic methods can detect small temperature changes caused by transformations between mechanical and thermal energy during a cyclic loading. This allows a use of the thermographic methods for fatigue testing. This contribution is focused on a development of an online thermographic method for fatigue limit evaluation during a sample cyclic loading. A novel 2D approach of fatigue limit evaluation is introduced. It brings a pixel wise view, which advantages compared to a standard 1D evaluation are demonstrated. It is presented a good correlation of results obtained by a standard Wöhler curve based evaluation and by thermographic methods.
