Special Issue Information

Dear Colleagues,

In addition to experimental research, mechanical engineering is now also focusing on assessing the behavior of various engineering structures using computational methods such as, but not limited to, the finite element method. This Second Edition of Materials is a continuation of the Special Issue on “Computational and Experimental Modeling of Interfaces and Joints in Advanced Materials”, which will focus on critical findings, advances and applications of numerical and experimental methods in all mechanical engineering fields related to structural connections of advanced materials. Papers dealing with new developments in relation to theoretical, computational, experimental and modeling techniques and their applications in science and technology will be considered. Papers that cover a wide range of issues are welcome, including (but not limited to) the following topics:

  1. Finite element analysis;
  2. Computational and experimental modeling;
  3. Structural health monitoring;
  4. Interfaces and their connections;
  5. Connections in mechanical engineering;
  6. Deformation analysis;
  7. Geometric modeling.

We look forward to hearing from you.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 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.

This study presents a calibrated modelling approach for predicting the abrasive wear of copper-free composite friction materials. Four formulations were analysed, including a copper-containing reference material and three experimental compositions in which copper was replaced by different aluminium/polytetrafluoroethylene ratios. Dry ball-cratering tests were performed to determine the apparent wear-rate coefficient under controlled laboratory conditions. The copper-containing reference material showed the lowest wear-rate coefficient, kc = 80.655 × 10−14 m2·N−1, whereas the copper-free formulations reached kc = 111.811 × 10−14 m2·N−1, 98.586 × 10−14 m2·N−1 and 90.579 × 10−14 m2·N−1 for S2, S3 and S4, respectively. Thus, copper replacement increased the apparent wear-rate coefficient by approximately 12–39%, depending on the Al/PTFE ratio. The obtained data were used to develop and compare four calibrated predictive models. Among them, the modified Hertz–Archard model, which included effective hardness and contact-related descriptors, provided the best agreement with the experimental data. This model achieved MAPE = 1.5%, RMSE = 2.181 × 10−14 m2·N−1 and a maximum absolute error of 4.3%, with all predictions within the ±5% error band. The results indicate that the proposed calibration framework can support preliminary screening and ranking of copper-free friction-material formulations under the adopted dry ball-cratering conditions.
