Critical experiments, measurements, and analyses to establish a crack arrest methodology for nuclear pressure vessel steels. Task 62. Eighth quarterly progress report, July--September 1976
Progress is reported in studies aimed at developing a testing practice for measuring K/sub Im/, the crack arrest material property of both unirradiated and irradiated steel samples. The merits of the crack-line and wedge loaded single-edge-notched (SEN) specimen as a crack arrest test piece have been investigated. Two-dimensional, dynamic finite difference computations of run-arrest events were carried out on ordinary-and duplex-SEN configurations. In addition to the theoretical calculations, 8 crack arrest experiments on shallow grooved SEN test specimens of A533B steel are described. The feasibility of using electron beam welded ''compound'' specimens to reduce irradiated material requirements for fracture toughness and crack arrest tests is evaluated.
