Recent advancements in geomechanics have highlighted the critical importance of understanding geomaterial behaviour across micro and macro scales. The integration of innovative experimental methods with advanced numerical modelling is pivotal for tackling the complex challenges posed by modern geotechnical and environmental demands. Techniques such as Discrete Element Method (DEM) simulations, coupled hydro-mechanical analyses (e.g., FEM-CFD or DEM-CFD coupling), and micro-mechanistic studies have greatly enhanced our understanding of geomaterials and their implications in geotechnical systems, providing actionable solutions for mitigating natural and man-made hazards.

Simultaneously, breakthroughs in artificial intelligence (AI) and data-driven constitutive modelling are revolutionising geomechanics, while nature-based techniques, such as bio-cementation and fungal-based methods, are offering green alternatives to conventional engineering practices. These advancements promise to deliver more efficient, sustainable, and resilient solutions across a wide range of applications, including foundation engineering, slope stability, coastal erosion mitigation, and other engineering geological challenges.

In line with the themes of the 21st UK Travelling Workshop (GM3) - Geomechanics: From Micro to Macro, to be held at the University of Liverpool on 16–17 December 2024, we are pleased to invite submissions for a Special Issue of Journal of Rock Mechanics and Geotechnical Engineering. This special issue aims to showcase cutting-edge research and interdisciplinary approaches that bridge the gap between the microscopic properties of geomaterials and their macro-scale engineering applications.

Topics of Interest

We welcome submissions on (but not limited to) the following topics:

• Advanced Laboratory and Field-Testing Methods
  Innovations in testing techniques for characterising micro and macro behaviours of geomaterials.
• State-of-the-Art Numerical Modelling in Geomechanics and Geotechnics
  Including coupled multi-physics simulations and the development of novel computational frameworks.
• AI-Driven Techniques in Geomechanics
  Applications of machine learning, data-driven modelling, and AI-enhanced decision-making in geotechnical engineering.
• Nature-Based Solutions in Geomechanics
  Sustainable and biomimetic solutions such as bio-cementation, fungal-based methods, and eco-geotechnics.

Submission and Participation

While we strongly encourage participants of the 21st UK Travelling Workshop GM3 to submit manuscripts inspired by the event’s discussions, contributions are also welcome from all researchers working in related fields. This special issue seeks to provide a dynamic platform for advancing knowledge, fostering innovation, and inspiring cross-disciplinary collaboration to address pressing challenges in geomechanics.
