Fatigue crack growth analysis of hydrogel by using peridynamics
This study presents an application of bond-associated non-ordinary state-based peridynamics (PD) and the corresponding fatigue theory to predict fatigue crack growth in hydrogel. The constitutive model of the hydrogel is assumed to be the neo-Hookean material. Fatigue process is viewed as a series of quasi-static crack growth and solved by the explicit method. The applied strain energy-based fatigue criterion is obtained from hydrogel fatigue experiments. The fidelity of this model is established by simulating the relevant experiment. Due to the limitation of the test data, only crack growth phase of fatigue life of hydrogel is focused on. The progressive damage predictions by PD agree with that of experiment and capture the general characteristics of the experimentally observed damage patterns.
期刊介绍：
The International Journal of Fracture is an outlet for original analytical, numerical and experimental contributions which provide improved understanding of the mechanisms of micro and macro fracture in all materials, and their engineering implications.
The Journal is pleased to receive papers from engineers and scientists working in various aspects of fracture. Contributions emphasizing empirical correlations, unanalyzed experimental results or routine numerical computations, while representing important necessary aspects of certain fatigue, strength, and fracture analyses, will normally be discouraged; occasional review papers in these as well as other areas are welcomed. Innovative and in-depth engineering applications of fracture theory are also encouraged.
In addition, the Journal welcomes, for rapid publication, Brief Notes in Fracture and Micromechanics which serve the Journal''s Objective. Brief Notes include: Brief presentation of a new idea, concept or method; new experimental observations or methods of significance; short notes of quality that do not amount to full length papers; discussion of previously published work in the Journal, and Brief Notes Errata.
