Fractal Theory Applications in the Contact Interface of Mechanical Equipment

Dear Colleagues,

Fractal theory, a mathematical tool used to describe complex and irregular shapes in nature, has been introduced into the field of mechanical equipment. In the study of contact interfaces in mechanical equipment, fractal theory demonstrates its unique advantages. It can delicately depict the microstructure of contact surfaces, providing a new perspective for contact mechanics analysis of mechanical equipment. Revealing the complex morphological patterns of interfaces aids in understanding the tribological characteristics and performance degradation mechanisms of mechanical equipment. By applying fractal theory, we can gain a deeper understanding of the contact mechanics and tribological properties of mechanical equipment, thereby optimizing equipment design and improving its performance and durability.

The focus of this Special Issue is to advance research on modeling methods for surface topography, tribological properties of contact interfaces, mechanical properties of contact interfaces, and cross-scale interface contact characteristics. Topics of interest include (but are not limited to) the following:

• Surface topography modeling methods;
• Tribological properties of contact interfaces;
• Mechanical properties of contact interfaces (contact stiffness, contact damping, etc.);
• Improvements to interface contact models;
• Cross-scale interface contact characteristics;
• Interface contact characteristics under lubricating 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 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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fractal and Fractional is an international peer-reviewed open access monthly journal published by MDPI.
