Static Friction Coefficients for Wheat Grains and Cast Iron

14.8 KB of calibrated contact parameters for wheat grains, including static friction coefficients of 0.426 against white cast iron and 0.322 between grains. Huapo Jia published this data on figshare in April 2026 to support discrete element modeling of wheat fracture. The dataset provides a foundation for simulating anisotropic grain behavior in roller milling processes.

Use Cases

• Calibrating discrete element models for wheat grain fracture based on the provided contact and crushing parameters.
• Simulating wheat grain interactions with roller mill surfaces based on the measured friction and restitution coefficients.
• Validating angle of repose simulations for granular wheat assemblies using the experimentally derived parameters.
• Optimizing wheat milling process parameters using the calibrated Tavares crushing model.

Strengths

• Parameters are validated with a low angle of repose simulation error of 1.05%.
• Fracture force and energy predictions show relative errors of 4.47% and 1.27%, indicating quantitative validation.
• Data is openly licensed under CC-BY-4.0.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 14.8 KB file size suggests a very limited scope, likely containing only the core parameter values.
