Fracture-toughness tests and displacement and crack-stability analyses of round-bar bend specimens of liquid-phase-sintered tungsten. Final report
Technical Report
·
OSTI ID:5835708
Plane strain fracture toughness tests were performed using the recently proposed round bar bend test procedure with a liquid-phase sintered tungsten alloy. The tests included a direct comparison of fracture toughness from rectangular and round bend specimens and measurements of load line compliance using the unloading technique of J integral fracture tests. Complementary displacement and crack growth stability analyses of the round bar were performed as an extension of recent work in these two areas.
