Special Issue Information

Dear Colleagues,

The purpose of this Special Issue is to highlight the influence of thermomechanical fatigue, creep, low cycle fatigue, and plasticity on aerospace systems and aircraft engines. The necessity of understanding the fatigue, creep, and their interaction in various mechanical components, subjected to different thermal and mechanical loads, is to accurately estimate the life of the components, which would help in developing proper maintenance schedules, improving the efficiency of the mechanical systems, and preventing catastrophic failures. The main topics covered in this Special Issue are computational, and experimental analysis of low-cycle and high-cycle fatigue, including crack initiation and propagation, creep, and creep–fatigue interaction in the domain applications of aircraft engines and space launchers. This Special Issue covers but is not limited to aerospace components undergoing thermomechanical fatigue, creep, and localized yielding. This Special Issue allows scientists and engineers to publish their studies of current interest in the computational and experimental fields of research.

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.

The Italian Ministry of University and Research (MIUR) funded the HYPROB Program to develop regeneratively cooled liquid rocket engines. In this type of engine, liquid propellant oxygen–methane is used, allowing us to reach very good performances in terms of high vacuum specific impulse and high thrust-to-weight ratio. The present study focused on the HYPROB final ground demonstrator, which will be able to produce a 30 kN thrust in flight conditions. In order to achieve such a thrust level, very high chamber pressures (up to 50 bar) and consequently high thermal fluxes and gradients are expected inside the thrust chamber. Very complex and high-fidelity numerical FEM models were adopted here to accurately simulate the thermal–mechanical behavior of the thrust chamber cooling channels, accounting for plasticity, creep, and low-cycle fatigue (LCF) phenomena. The aim of the current work was to investigate the main failure phenomena that could occur during the thrust chamber’s service life. Results demonstrated that LCF is the main cause of failure. The corresponding number of loading cycles to failure were calculated accordingly. Full article
