Quantitative thermoelastic stress analysis by means of low-cost setups

•A micro-bolometer and a simple script are used for thermoelastic stress analysis.•A camera dependent calibration allows quantitative stress measurements.•Spectral leakage and frames missing errors have been quantified and corrected.•The SIF and crack tip position in fatigue tests are obtained from...
