Wheat Grain Fracture Simulation Parameters and Calibration Results

A study by Huapo Jia provides calibrated contact and crushing parameters for wheat grains using the Tavares model. The dataset includes specific coefficients for wheat-to-iron and wheat-to-wheat contacts, fracture energy distribution, and validation metrics. It was last updated on 2026-04 13 and is shared under a CC-BY-4.0 license.

Use Cases

• Calibrating discrete element method (DEM) models for wheat grain fracture based on the provided contact coefficients.
• Validating simulation accuracy for wheat roller milling processes using the calibrated Tavares model parameters.
• Analyzing the anisotropic fracture behavior of wheat grains based on the log-normal fracture energy distribution.
• Optimizing wheat processing equipment design using the experimentally validated force-displacement relationship.

Strengths

• Includes specific calibrated parameters: elastic restitution, static friction, and rolling friction coefficients for two contact types.
• Model validation shows low error rates: 1.05% deviation for angle of repose and 4.47% for fracture force.
• Fracture energy distribution is characterized with a median value of 2069.78 J/kg and a cumulative damage coefficient of 5.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is small (24.6 KB), indicating limited scope, likely containing only the core simulation results and parameters.
