Experimental Investigation and Numerical Modeling of Rock Brittle Failure Behavior under High Stress Conditions

Dear Colleagues,

Recent years have witnessed a clear trend of developing deeper and longer tunnels to meet the growing needs of the mining, hydropower, and transportation industries. The demands for exploration of underground space, energy, and resources have necessitated the safe construction of underground tunnels. At the same time, underground transport becomes an appealing solution to address urbanization problems and facilitate connections between cities. The failure behavior of deep underground rocks under high stress becomes an important issue in rock mechanics and is of great significance to stability evaluation in rock engineering practices, such as underground excavation, shale gas production, and deep tunnel transportation. High stress applied on rocks makes their failure much different and more complex. Therefore, it is of great importance to assess the failure mechanism of brittle rock under high stress conditions.

Some new laboratory experimental techniques and numerical simulation methods for understanding rock mechanical behavior have appeared in recent years. This Research Topic aims to highlight the influence of high stress on the failure behaviors and mechanical properties of brittle rock under high stress. Submissions of original research articles, review articles, and case studies are all welcome.

Potential topics include, but are not limited to:

• Failure mechanism of brittle rock under high stress
• Mechanical properties of brittle rock under high stress
• Damage constitutive model of brittle rock under high stress
• Analysis and evaluation of deep rock engineering
• New numerical simulation method for deep brittle rock
• New technology of deep brittle rock test

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. 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.
