Wheat Grain Fracture Model Calibration Data for Discrete Element Simulation

Calibration data for the Tavares crushing model of wheat grains, including contact and fracture parameters. The dataset contains experimentally derived coefficients for wheat-to-wheat and wheat-to-cast-iron interactions, and log-normal fracture energy distribution parameters. It was authored by Huapo Jia and last updated on April 13, 2026.

Use Cases

• Calibrating discrete element method (DEM) simulation parameters for wheat grain fracture based on the provided contact coefficients.
• Validating anisotropic grain fracture models in agricultural processing simulations based on the described Tavares model calibration.
• Optimizing wheat roller milling process parameters using the calibrated force-displacement relationship data.
• Comparing simulated and experimental angles of repose for granular wheat assemblies based on the validated friction coefficients.

Strengths

• Parameters are quantitatively validated with low error rates, such as a 1.05% deviation for the angle of repose.
• Specific calibrated coefficients are provided, including elastic restitution, static friction, and rolling friction values for two contact types.
• Fracture energy distribution is characterized with a median value of 2069.78 J/kg and a cumulative damage coefficient of 5.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (10.3 KB), indicating a limited scope focused on calibration parameters rather than extensive experimental results.
