Description

X-ray synchrotron radiation of high (11 KeV) energy and high flux (10{sup 10} photons per square centimeter per second) has been used to measure strains and polycrystallinity in 6-mm thick polycrystalline beryllium compact tension (CT) specimens at and around the crack tip (for fatigue-precracked sample) or at chevron notch point under load or no-load conditions. The authors demonstrated the feasibility strain field mapping as well as determining the polycrystallinity at or near the points of maximum load in beryllium CT specimens. The experimental techniques and results will be discussed.
