Lock-in thermography and fatigue limit of metals
Proceedings of the 2000 International Conference on Quantitative InfraRed Thermography, 2000 Thermography was performed on stainless steel 316L and aluminium alloy 7010 samples as they were submitted to a sinusoidal mechanical stress (traction/compression). For each stress amplitude value the temperature data were recorded in 5 s. A specific signal demodulation procedure was used to extract the first two Fourier components and the mean ...

Crack path for run-out specimens in fatigue tests: is it belonging to high- or very-high-cycle fatigue regime? [PDF]
Fracture and Structural Integrity, 2015 Fatigue tests run-out specimens up to 106 – 5x107 load cycles are used to determine the stress level named “fatigue limit”. Nevertheless, it is not clear what kind of fatigue cracking takes or will take place in these specimens.

Comparison of Analysis Methods of Data from Thermographic Measurements of Al 2024 Fatigue Limit For R=0.1 [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 The traditional methods for fatigue characterization of metallic materials are expensive and extremely time consuming. In order to overcome these shortcomings, the Thermographic Method (TM), based on thermographic analysis, is applied to estimate the ...
