About this Research Topic
Understanding and predicting the response of granular-based systems in applications thus requires a detailed knowledge of the connection of basic building blocks and their interactions with the macroscale properties of the systems considered. Developing such connections requires better understanding of the relevant physical mechanisms on the scales that range from micro, to meso and macro. While significant progress has been reached during last decades on understanding relevant physical mechanisms, there is still much to be learned about these systems.
Despite many aspects of common interest in the field of granular materials, it has proven to be challenging to stimulate sustained interaction between different communities, e.g. geomechanics, physics, engineering, and applied mathematics. This Research Topic aims to bring together contributions of recent research on numerical, experimental, and theoretical approaches towards granular materials in view of exchanging recent advances.
We envision the Research Topic bringing together a multi-disciplinary group of researchers that will discuss a wide range of topics concerning the physics of dense granular matter, including but not limited to new experiments considering dry and wet granular systems as well as suspensions, discrete element method/molecular dynamics, simulations of granular materials, various methods developed recently to quantify the internal structure of granular systems, as well as new continuum and mesoscopic models bridging between static and flowing systems. We expect this issue will help to shape the research in this area in the future.
The subjects covered by this Research Topic include:
- Connecting theory, modeling and experiments
- Deformation and failure of granular assemblies
- Dilatancy and critical state of densely packed granular materials: statics and kinematics
- The dynamics of landslides, debris flows, and avalanches: theory and experiments
- Nonlocality and yield in granular materials
- Jamming and un-jamming transitions
- Patterns and clustering in dense granular materials
- From grains to composite materials, e.g., concrete or clay
Keywords: Granular Assemblies, Static, Creep, Numerical Modeling, Experiment Investigation, Theoretical Framework, Deformation and Failure, Force Network
