The Damage and Fracture Analysis in Rocks and Concretes

Dear Colleagues,

Rocks and concretes are main building materials widely utilized in the fields of underground mining, tunnelling, civil infrastructure constructions, etc. The damage and fracture process under natural and human-induced conditions are of particular importance for the aforementioned fields, and have therefore long been a research focus of scholars interested in rock mechanics and geotechnical engineering. In this context, this Special Issue features a variation in scales. For example, on a smaller scale, dislocations of the mineral crystal lattice and boundary cracks in rocks cause stress concentrations, which may be seen as the location of damage and serve as a potential source for further crack development. On a larger scale, large faults that may lead to earthquakes are also related to fracture issues. Uncertainty exists in describing the location, shape and condition of natural fractures in rocks, which in turn results in uncertainty in the initial stress fields. Regarding human-induced fractures, comprehensive knowledge of the fracturing processes and mechanisms is also of vital importance for human activities such as rock fragmentation in mining and rock cutting in tunnelling.

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. Buildings 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.
