# Axial Load Transfer Mechanism in Fully Grounded Rock Bolting System: A Systematic Review
## 3 Analysis and Results
### Descriptive Results
#### 3.1.4. Researchers Leading Research on Axial Load Transfer Mechanism of FGRBSs  
VOSviewer was also employed to identify key researchers in the field. Utilising co-authorship data, it revealed collaborations among 225 authors on publications related to the axial load mechanism of FGRBSs. By setting a minimum threshold of three articles per author, a group of 12 leading researchers emerged (Table 3). Notably, [PERSON] stands out as the most prolific researcher, having published the highest number of articles (six) and garnering the most citations (362). [PERSON] and [PERSON] follow closely, each contributing five articles and receiving impressive citation counts of 320 and 318, respectively. \begin{table}

Table 2: Top 10 contributing institutions in Web of Science (1988–2024). Red cluster: this cluster comprises [PERSON], [PERSON], and [PERSON], whose research spans three distinct areas: numerical simulation, analytical modelling, and experimental testing (all focused on investigating the axial load transfer mechanism). Their collaboration resulted in four publications (two on numerical simulation, one on analytical modelling, and one on experimental testing) between 2013 and 2017 that have garnered a total of 262 citations. Interestingly, for their numerical simulations, they employed the finite difference method (FDM) within Flac2D software to model the non-linear bond-slip behaviour of the debonding B-G interface in FGRBSs subjected to tensile loads. Green Cluster: This cluster comprises [PERSON], [PERSON], and [PERSON]. Their research focuses on developing analytical approaches to evaluate the load-displacement relationship and confining pressure's influence on the axial load transfer mechanism in FGRBSs. Notably, [PERSON] collaborated with [PERSON] on three articles (cited 37 times) and [PERSON] on two separate articles (cited 52 times). Interestingly, their most recent collaboration in 2023 has already garnered 21 citations. All their models were directly calibrated from pull-out experimental tests.
