DETECTION OF FATIGUE CRACKS IN EYEBARS USING TIME OF FLIGHT DIFFRACTION

This paper examines the development of a Time of Flight Diffraction (TOFD) ultrasonic method for defect detection and sizing in eyebars. Eyebars from the Pasko - Kennewick bridge are utilized as test specimens to determine eyebar fatigue performance, and to test the effectiveness of the TOFD method. The test setup for making crack depth measurements in eyebars is described. Measured results of the depth of machines slot test specimens and results of fatigue crack growth are presented.
