Multiphysics Modeling for Fracture and Fragmentation of Geomaterials

Dear Colleagues,

With the development of computer hardware and numerical algorithms, numerical modeling has become more and more widely used in geomechanics and civil engineering. Some novel numerical algorithms are constantly being proposed, such as finite element method, boundary element method, discrete element method, discontinuous deformation analysis, numerical manifold method, finite-discrete element method (FDEM), etc. The instability and failure of various geotechnical engineering are often inseparable from the initiation, propagation, and interaction of micro-cracks within the geomaterial and its fragmentation. In many engineering problems, the initiation, propagation, and interaction of cracks in geomaterials and their fragmentation are often developed under the effect of fluid, heat, mechanics, and even chemistry, which adds to the complexity of the engineering problems. These difficult problems pose a significant challenge to numerical modeling but also provide a new opportunity for its development.

This Special Issue "Multiphysics Modeling of Fracture and Fragmentation of Geomaterials" aims to attract new contributions in this field.

Our topics include, but not limited to:

• Model development and application of finite-discrete element method (FDEM) for multiphysics modeling of fracture and fragmentation of geomaterials;
• Novel numerical methods and algorithms for multiphysics modeling of fracture and fragmentation of geomaterials, such as discrete element method (DEM), discontinuous deformation (DDA), numerical manifold method (NMM), phase field method, peridynamics (PD), material point method (MPM), and smoothed particle hydrodynamics (SPH);
• Parallel algorithms for modeling of fracture and fragmentation of geomaterials (OpenMP, MPI, GPU);
• Numerical modeling on hydraulic fracturing in naturally fractured reservoirs or enhanced geothermal systems (EGS);
• Modeling soil, rock, and concrete blasting;
• Modeling soil shrinkage cracking, concrete or rock fracture and fragmentation;
• Modeling tunnel water inrush;

• Modeling geotechnical engineering in the cold region;

• Modeling landslides or slope failure;
• THMC coupling processes in nuclear waste disposal, underground energy or CO2 storage and energy development (geothermal energy, oil, gas, etc.)

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-anonymized 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.
