Special Issue Information

Dear colleagues,

This Special Issue is related to the 25th International Congress of Theoretical and Applied Mechanics (25th ICTAM), which will take place in Milan (Italy) from 22 to 27 August 2021. The 25th ICTAM was initially scheduled from 23 to 28 August 2020 and postponed due to the COVID-19 pandemic. This conference is organized by the Italian Association of Theoretical and Applied Mechanics, in collaboration with the Polytechnic University of Milan and University of Pavia.

The 25th ICTAM involves many research topics in engineering, mathematical modeling, biology, etc. Accordingly, this Special Issue seeks updated and new knowledge to shape future research directions in theoretical and applied mechanics.

Our purpose is to investigate advanced topics in mechanics by different researchers from around the world. In this Special Issue, we invite and welcome review, expository, and original papers dealing with recent advances in theoretical and applied mechanics and, from a more general point of view, all theoretical and practical studies focused on this topic. It also welcomes other papers within this field but not from the conference.

The main topics of this Special Issue include (but are not limited to):

  1. Nonlinear dynamics;
  2. Fluid mechanics;
  3. Acoustics;
  4. Geophysics and geomechanics;
  5. Wave propagation;
  6. Nanostructures and MEMS;
  7. Metamaterials;
  8. Porous media.

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. Applied Sciences 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 2400 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.

For fault diagnosis and predictive maintenance of rotating machinery, the phase errors generated by the integration processing of a vibration signal are an essential investigation subject. Phase errors affect the solution of mechanical systems with multiple vibration sources and also the information transmitted through the vibration that is used for fault diagnosis. This work proposes the use of phase plane, recurrence plot (RP), and cross recurrence plot (CRP) to evaluate phase shift error effects on the solution of multiple asynchronous and simple periodic functions, and on the smoothing of a Gaussian peak with white noise. Noisy peaks were smoothed twice with the triangular method and with a different number of points. The analysis of the asynchronous periodic functions and the smoothing indicated that a small phase shift changes the phase plane and the RP pattern. These changes can affect not only the accuracy of machinery fault diagnosis but also prediction for the application of timely maintenance actions. Full article
