A Literature Review of Incorporating Crack Tip Plasticity into Fatigue Crack Growth Models

Materials (Basel). 2023 Dec 11;16(24):7603. doi: 10.3390/ma16247603.

Abstract

This paper presents an extensive literature review focusing on the utilisation of crack tip plasticity as a crucial parameter in determining and enhancing crack growth models. The review encompasses a comprehensive analysis of various methodologies, predominantly emphasising numerical simulations of crack growth models while also considering analytical approaches. Although experimental investigations are not the focus of this review, their relevance and interplay with numerical and analytical methods are acknowledged. The paper critically examines these methodologies, providing insights into their advantages and limitations. Ultimately, this review aims to offer a holistic understanding of the role of crack tip plasticity in the development of effective crack growth models, highlighting the synergies and gaps between theoretical, experimental, and simulation-based approaches.

Keywords: crack closure (CC); linear elastic fracture mechanics (LEFM); linear elasto–plastic fracture mechanics (LEPFM); stress intensity factor (SIF).
