Special Issue Information

Dear Colleagues,

As Editorial Board Members of Modelling, we are pleased to announce a Special Issue entitled "Feature Papers of Computational Modelling and Simulation for Fatigue and Fracture of Engineering Materials and Structures". This Special Issue will be a collection of high-quality papers from Editorial Board Members and leading researchers invited by the Editorial Office. Both original research articles and comprehensive review papers are welcome.

Fatigue and fracture are critical factors that affect the safety and reliability of engineering structures and mechanical systems. Computational modelling and simulation have become essential tools in understanding and predicting the behaviour of materials and structures under fatigue and fracture conditions. New computational approaches are being developed to enable the more accurate and efficient modelling of fatigue and fracture. Also, the development of new materials and applications demands reliable simulation tools.    

This Special Issue aims to collect reference papers on, but not limited to, the following topics of interest:

  • Advanced computational methods for fatigue and fracture analysis (e.g., phase-field techniques; peridynamics; meshless; crystal plasticity);
  • Multi-scale modelling and simulation of fatigue and fracture;
  • Damage mechanics and failure analysis of engineering materials and structures;
  • Probabilistic modelling and reliability analysis of fatigue and fracture;
  • Experimental validation of computational models and simulations;
  • Applications of computational modelling and simulation in the design and optimization of engineering structures;
  • Modelling of fatigue crack initiation and propagation and multiaxial fatigue;
  • Modelling of advanced materials;
  • Modelling of corrosion-assisted fatigue and fracture (e.g., H2 embrittlement);
  • Surrogate modelling (e.g., data-driven models, ANNs).

Submissions should be original and not have been published or submitted elsewhere. All papers will be peer-reviewed by at least two experts in the field, and accepted papers will be published in the Special Issue of the journal.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Modelling is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

The purpose of this study is to investigate the effective behaviour of a micro-cracked material whose matrix bulk and shear moduli are ruled by a linear viscoelastic Burgers model. The analysis includes a detailed study of randomly oriented and distributed cracks displaying an overall isotropic behaviour, as well as aligned cracks resulting in a transversely isotropic medium. Effective material properties are approximated with the assumption that the homogenized equivalent medium exhibits the characteristics of a Burgers model, leading to the identification of short-term and long-term homogenized modules in the Laplace–Carson space through simplified formulations. The crucial advantage of this analytical technique consists in avoiding calculations of the inverse Laplace–Carson transform. The micromechanical estimates are validated through comparisons with FE numerical simulations on 3D microstructures generated with zero-thickness void cracks of disc shape. Intersections between randomly oriented cracks are accounted for, thereby highlighting a potential percolation phenomenon. The effects of micro-cracks on the material’s behaviour are then studied with the aim of providing high-performance creep models for macrostructure calculations at a moderate computation cost through the application of analytical homogenization techniques.

This study develops a rapid algorithm coupled with the finite element method to predict the fatigue crack propagation process and select the enhancement factor for the equivalent random load spectrum of accelerated fatigue tests. The proposed algorithm is validated by several fatigue tests of an aluminum alloy under the accelerated random load spectra. In the validation process, two kinds of panels with different geometries and sizes are used to calculate the stress intensity factor, critical crack length, and crack propagation life. The simulated and experimental findings indicate that when the aluminum alloy is in a low plasticity state, the crack propagation life exhibits a linear relationship with the acceleration factor. When the aluminum alloy is in a high plasticity state, this study proposes an empirical formula to calculate the equivalent stress intensity factor and crack propagation life. The normalized empirical formula is independent of the geometry and size of different samples, although the fracture processes are different in the two kinds of panels used in our study. Overall, the numerical method proposed in this paper can be applied to predict the fatigue crack propagation life for the random spectrum of large samples based on the results of the simulated accelerated crack propagation process and the accelerated fatigue tests of small samples to reduce the cost and time of the testing.
