Special Issue Information

Dear Colleagues,

The development of computer methods for the solution of scientific and engineering problems was one of the great scientific and engineering achievements of the second half of the 20th century, with a profound impact on science and technology. Since that time, computer-aided modeling of physical and mechanical processes has been becoming more and more popular every year. This is convincingly evidenced by a rapid increase in the number of publications, where computer modeling is used to solve various problems that cannot be solved by other known methods. Modern computer methods and computing power allow us to accurately reproduce complex processes and take into account many factors responsible for the physics of the phenomenon under study, which opens up wide prospects for obtaining new knowledge. This applies completely to the solution of tribological problems as well.

Volume one of the Special Issue on “Computer Simulation in Tribology and Friction” has attracted great attention among scientists; thus, we have decided to launch volume two, with the same aims of publishing the latest research in using various computer-aided modeling methods for resolving wear and friction problems. Contributions from both academic and industrial researchers are welcome. Accepted papers should aid either in obtaining new knowledge in the field of tribology or in providing deep insight into developing new computer-aided modeling approaches and directions to resolve the problems of wear and friction.

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. Lubricants is an international peer-reviewed open access monthly 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.

Adhesive contact between a flat brush structure with deformable microfibrils and an elastic half space is numerically simulated. The stiffness of pillars is modeled by linear springs. The fast Fourier transform-assisted boundary element method for the contact of rigid indenters is modified to include the microfibril stiffness so that the deflection of pillars and elastic interaction to elastic foundation are coupled. In the limiting case of rigid pillars (pillar stiffness is much larger than the contact stiffness), the adhesive force is determined by the filling factor of brush, as described earlier. In the case of very soft pillars, the adhesive force is proportional to N1/4, where N is the number of pillars. The influence of relative stiffness, number and distribution of pillars on adhesive force is studied numerically. The results from both regularly and randomly distributed pillars show that the adhesive force is enhanced by splitting a compact punch into microfibrils and this effect becomes larger when the fibrils are softer.
