Fracture Toughness Tests and Displacement and Crack Stability Analyses of Round Bar Bend Specimens of Liquid-Phase Sintered Tungsten

Abstract

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.
