Measurement of Stress Corrosion Cracks in Aluminum Alloy DCB Specimens Using an Ultrasonic Pulse-Echo Technique.
Abstract
This program evaluated a non-destructive ultrasonic method for monitoring crack growth rate. Aluminum alloy test specimens were used to calibrate the equipment and to assess the measurement accuracy and reproducibility. Together, the optical and ultrasonic techniques could lead to a more accurate assessment of stress corrosion crack growth in aerospace alloys through obtaining a truer picture of interior crack front shapes.
