Special Issue Information

Dear Colleagues,

Metallic materials are one of the largest groups used to produce machine components and structures. Moreover, the development of technology enables the creation of new alloys of these materials that also affect their individual characteristics depending on their production method. Therefore, the impact of these features on durability and mechanical strength requires knowledge of the damage mechanisms and their development under static and cyclic loadings.

Experimental research allows for understanding the damage mechanism, analyzing it in depth and providing information for computer simulations.

The Special Issue is devoted to the development of experimental and theoretical methods of evaluation and a description of the behavior of metallic materials subjected to fatigue loads, including but not limited to the following topics:

  • Uniaxial and multiaxial fatigue;
  • Damage mechanisms;
  • Damage accumulation models;
  • Fatigue crack growth;
  • Mixed-mode fracture;
  • Fatigue life assessment;
  • Failure analysis;
  • Metal composites.

In this Special Issue, we will explore the research progress made in understanding materials and structures' fatigue and failure mechanisms. Therefore, we kindly invite researchers and practitioners to share their expertise and insights.

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. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Surface integrity is a critical factor that affects the fatigue resistance of materials. A surface mechanical rolling treatment (SMRT) process can effectively improve the surface integrity of the material, thus enhancing the fatigue property. In this paper, an analysis of variance (ANOVA) and signal-to-noise ratio (SNR) are performed by orthogonal experimental design with SMRT parameters as variables and surface integrity indicators as optimization objectives, and the support vector machine-active learning (SVM-AL) model is proposed based on machine learning theory. The entire model includes three rounds of AL processes. In each round of the AL process, the SMRT parameters with relative average deviation and high output values from cross-validation are selected for the additional experimental supplement. The results show that the prediction accuracy and generalization ability of the SVM-AL model are significantly improved compared to the support vector machine (SVM) model. A fatigue test was also carried out, and the fatigue property of the SMRT specimens predicted by the SVM-AL model is also higher than that of the other specimens. Full article
