Special Issue Information
Dear Colleagues,
O-ring fatigue life is a key determinant of sealing reliability in valves, pumps, and aerospace actuators operating under cyclic pressure/temperature, media exposure, and variable squeeze. Damage accumulation—micro-crack initiation, viscoelastic softening, and extrusion/nibbling—alters contact stress and can cause early leakage. Advances in materials, testing, and multiphysics modeling enable more accurate life prediction and mitigation strategies.
This Special Issue invites original research and reviews on fatigue and leakage of O-rings, including pressure/thermal cycling and accelerated aging, media compatibility, in situ leakage/strain monitoring, FE-based hyperelastic–viscoelastic modeling, contact and thermal–fluid–structure coupling, crack-growth and energy-based approaches, and the roles of material formulation, surface roughness, squeeze ratio, and groove design. Studies on uncertainty, reliability, and data-driven diagnosis/prognosis are also encouraged, with applications spanning cryogenic, aerospace, oil-and-gas, and chemical services.

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.
