Fatigue of Polymers and Composite Materials: From the LCF to the VHCF Life Range

Dear Colleagues,

Research on the structural integrity of polymers and composite materials is fundamental for designing safe but lightweight components, especially in industrial applications, e.g., automotive and aerospace, for which strict regulations in terms of CO2 emissions and sustainability are mandatory. Among the loads which mostly affect the structural integrity of these materials, cyclic loads are particularly critical. The fatigue response should therefore be experimentally assessed and reliably modelled. Moreover, the durability of components has significantly increased in recent years, with possible failures occurring due to low-amplitude stress at a very high number of cycles.

The present Special Issue aims to provide an overview of the most recent advances in the field of the fatigue response of polymers and composite materials. Research activities on conventional or advanced fatigue testing methodologies (e.g., ultrasonic fatigue tests) are welcome, with low-cycle fatigue (LCF), high-cycle fatigue (HCF), and very-high-cycle fatigue life ranges being investigated. Statistical modelling of fatigue data and numerical simulations of fatigue damage mechanisms are also fundamental for the design of polymers and composite materials, and therefore fit with the scope of this Special Issue.

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. 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.
