DFN Distribution Characteristics: Synthetic Rock Mass Data on Size Effect

Synthetic rock mass data from discrete element method simulations of limestone-concrete composites. The dataset contains results from uniaxial compression tests analyzing strength, deformation, and failure features across different model sizes and joint dip angles. The 5.5 KB XLS file was authored by Hang Liu and last updated in March 2026.

Use Cases

• Modeling the size effect on uniaxial compressive strength (UCS) based on simulated composite dimensions.
• Analyzing the influence of joint dip angle on compressive modulus based on the described angle ranges.
• Studying failure mode transitions from global to dispersed localized failure based on described energy release patterns.
• Comparing the sensitivity of deformation characteristics versus strength characteristics to size variations based on the described difference ratios.

Strengths

• Data is derived from controlled synthetic rock mass models using the discrete element method (PFC).
• Analysis includes specific dimensional thresholds (e.g., 600 mm x 1200 mm) where UCS stabilizes.
• Examines specific joint dip angle ranges (e.g., 75°–80°, 30°–35°) with pronounced effects.

Limitations

• Row count and column-level documentation are unknown; field semantics must be inferred after download.
• The dataset is very small (5.5 KB), indicating limited scope or a summary of results.
• Description metadata is limited; actual data quality and structure require manual inspection.
