Void nucleation in a low alloy steel Conference Paper uri icon

abstract

  • Void nucleation in a low alloy steel was studied both experimentally and computationally with the aim of identifying a macroscopic criterion for nucleation. Three types of circumferential notched cylindrical specimens were examined in order to vary the stress triaxiality in the notch region. The specimens were subjected to specified loads somewhat below the fracture loads. The microvoids initiated by the cracking of titanium nitride particles. The specimens were sectioned parallel to the loading axis and the locations of cracked and uncracked particles were identified. Finite element calculations were carried out for each specimen geometry based on conventional isotropic hardening plasticity theory. The ability of a potential void nucleation criterion to predict the location of the cracked particles is explored.
