Fracture testing of 2324-T39 aluminum alloy. Final report
Technical Report
·
OSTI ID:177685
Fracture tests were conducted on middle crack tension (M(T)) and compact tension (C(T)) specimens of 7.6 mm-thick 2324-T39 aluminum in the L-T orientation. The configurations tested included 102 mm-wide M(T), 305 mm-wide M(T), 152 mm-wide C(T), and 102 mm-wide C(T) specimens. The measured critical crack-tip opening angle (CTOA) for the 102 mm-wide M(T) tests, the 305 mm-wide M(T) tests, and the 152 mm-wide C(T) tests, after a small amount of crack extension, were 4.4, 4.9, 5.1 degrees, respectively. The scatter involved with these measurements was about +/- 1 degree.
