Crack Monitoring in Resonance Fatigue Testing of Welded Specimens Using Digital Image Correlation

¹Institute for Ship Structural Design and Analysis, Hamburg University of Technology (TUHH)

Digital image correlation is used in fatigue tests on a resonance testing machine to detect macroscopic cracks and monitor crack propagation in welded specimens. Cracks on the specimen surface become visible as increased strains.
