Special Issue Information

Dear Colleagues,

The mechanical behavior of composite materials is intrinsically complex, usually spanning multiple length scales, from the microscopic level of reinforcements to the macroscopic scale of overall structural performance. The multiscale nature of studying these materials poses significant challenges for accurate numerical modeling and predictive design.

This Special Issue is dedicated to advanced multiscale approaches for the analysis and optimization of composite materials, with a particular emphasis on integrating Finite Element Methods (FEMs) across different scales. Contributions that address innovative techniques to bridge micro-, meso-, and macroscale behaviors, enabling more accurate simulation of complex nonlinear phenomena such as damage, fracture, and buckling mechanisms, are welcome. A central focus is on numerical models that exploit FEM-based approaches to comprehensively investigate the role of microstructural evolutions in determining the overall stiffness, strength, and toughness properties of advanced composite materials.

While the primary focus of this issue is methodological, it also aims to highlight how these numerical techniques can accelerate the adoption of sustainable composite materials (e.g., bio-based or recycled-fiber composites) by significantly enhancing the predictability of their structural performance, and ultimately by making their optimal design more effective. Submissions that explore computational fracture mechanics aspects may also be considered if devoted to the advancement of modeling and simulation techniques pertaining to sustainable composite materials.

This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, combining bibliometric mapping and mechanistic synthesis to provide a unified evidence-based review of cementitious grouts in ground support systems. The bibliometric layer quantifies global research activity, while the systematic synthesis interprets how material composition, pozzolanic chemistry, and rheology control grout performance and sustainability. This study presents a systematic review complemented by bibliometric analysis to synthesise global research trends and technical advances in grout design. A dataset of 1200 articles was screened, from which 101 journal papers met the inclusion and quality criteria and were analysed in detail. Co-occurrence mapping of author keywords was then used to identify research hotspots and collaborative structures. The bibliometric analysis revealed that Construction and Building Materials is the leading outlet. Co-authorship mapping highlighted strong international collaboration, with leading clusters centred on supplementary cementitious materials, rheology, and microstructural analysis. The technical review consolidates five interrelated themes: reinforcement mechanisms, cementitious grouts, chemical reactions and pozzolanic reactivity, fresh and hardened state properties, and microstructural development with rheological behaviour. Across these themes, supplementary cementitious materials and waste-derived binders have emerged as central to both performance enhancement and carbon reduction, while advanced experimental and modelling techniques have refined understanding of microstructural evolution and grout–rock–bolt interactions. Collectively, the findings underline that cementitious grouts are no longer passive fillers but engineered composites designed for mechanical efficiency, durability, and environmental responsibility. Key research gaps remain in the standardisation of rheological testing, long-term durability under complex field conditions, and integration of life-cycle assessment into grout development. Addressing these challenges will be critical for the design of next-generation grouts capable of meeting the dual imperatives of safety and sustainability in mining and civil engineering.
