A Microscopic Mechanism of Fatigue Crack Growth Based on the Dislocation-Free Zone
Source abstract
Abstract
A new microscopic mechanism model of fatigue crack growth is presented based on the dislocation-free-zone (DFZ) theory. A cohesive zone model is developed to determine the stress filed of the DFZ under cyclic loading. A simple relation is derived to evaluate the rate of fatigue crack growth.
