FRACTURE EXPERIMENTS WITH CRACKED AND EMBRITTLED HEXCAN SECTIONS.
Crack-like flaws that might exist in hexagonal subassembly ducts are not generally expected to initiate brittle fracture, but there is reason to be concerned about the integrity of cracked hexcans that have been severely embrittled by fast-neutron irradiation. In order to check the applicability of linear elastic fracture mechanics analysis to such ducts, a program of experiments with deliberately cracked and embrittled hexcan sections has been undertaken. In this paper, a comparison of analytical predictions and experimental results are made and discussed.
