The mechanisms of ductile rupture - ScienceDirect

These questions are addressed by characterizing the fracture process in three high-purity face-centered cubic (FCC) metals of medium-to-high stacking fault energy: copper, nickel, and aluminum. These data demonstrate that, for a given stress state and material, several mechanisms frequently work together in a sequential manner to cause fracture.The mechanisms of ductile rupture (Journal Article) | DOE micromechanisms of ductile fracturing of dhA nitrogen-strengthened austenitic stainless steel was tested in uniaxial tension at room temperature (295 K) and in liquid nitrogen (76 K). A transition in ductile fracture appearance from a cup-cone fracture at room temperature to shear fracture at cryogenic temperature is observed and correlated to deformation behavior and micromechanisms (void nucleation and strain localization) of fracture.Qualitative and quantitative studies of fracture surfaces micromechanisms of ductile fracturing of dhNov 29, 2016 · This work shows the results of qualitative and quantitative studies about the micromechanisms of fracture found on tensile, fracture toughness, impact and fatigue precracking test specimens of ductile and grey cast irons having four different matrix microstructures (ferritic, pearlitic, ausferritic and bainitic) and three different piece sizes.

Then the transition between both modes of failure is investigated. It is shown that the DBT behavior observed in impact tests or in fracture toughness specimens can be reasonably well predicted using modern theories on brittle and ductile fracture in conjunction with FE numerical simulations.
