Wheat Grain Breakage Parameters for Discrete Element Modeling

5.5 KB of calibrated contact and crushing parameters for wheat grains, including coefficients for interactions with white cast iron and other grains. The dataset, created by Huapo Jia and last updated in April 2026, provides a foundation for simulating fracture behavior in wheat roller milling. It contains results from physical experiments and simulation used to validate a Tavares crushing model.

Use Cases

• Calibrating discrete element method (DEM) simulations for wheat milling based on provided contact coefficients.
• Modeling anisotropic fracture behavior of wheat grains based on the log-normal fracture energy distribution.
• Validating simulation accuracy for roller milling processes based on the comparison of force-displacement curves.
• Optimizing wheat processing equipment design based on the calibrated Tavares model parameters.

Strengths

• Includes specific calibrated coefficients (e.g., restitution coefficient of 0.399) validated with a 1.05% error in angle of repose tests.
• Model validation shows low relative errors for fracture force (4.47%) and fracture energy (1.27%).
• Dataset is openly available under a CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 5.5 KB size indicates a very small dataset, likely containing only parameter tables and not extensive experimental results.
