Nonlinear Work-Hardening Crack-Tip Fields by Dislocation Modeling

Source

The dislocation model is extended to include nonlinear hardening of the cracktip fields. The resulting model is applied to the loaded and unloaded crack. Several factors affecting the cyclic J-integral are discussed, including mean stress, Baushinger effects, and the applied far-field strain energy density.
