A methodology for simulating plasticity induced crack closure and crack shape evolution based on elastic-plastic fracture parameters

Mikel Escalero et al.

Summary: A new methodology for predicting fatigue crack growth in small and large scale yielding scenarios is proposed based on simulating plasticity induced crack closure and crack shape evolution. By simulating crack growth in a compact tension specimen subjected to small scale yielding conditions, the predicted crack shape shows high agreement with experimental observations, indicating the relevance of the proposed methodology for further crack growth studies.

Assessment of a numerical strategy for fatigue growth and shape evolution of a corner crack from a pin-loaded hole

F. Bovecchi et al.

Summary: The study investigates fatigue growth and shape evolution of a corner crack in a pin-loaded hole by means of three-dimensional FE analyses, reproducing experimentally measured crack front shapes through tuning the constraint factor/plasticity-induced crack closure strategy, and quantitatively determining the LEFM acceptability regions using elastic-plastic simulations. It assesses the sensitivity of crack propagation and shape evolution to various factors, such as stress distribution, relationship between J-integral and stress intensity factor, and changing propagation rates along different directions, with the proposed approach producing very accurate results in terms of crack propagation rate and shape evolution.
