Wheat Grain Contact and Fracture Parameters for Discrete Element Modeling

A dataset containing calibrated contact and crushing parameters for wheat grains, validated via angle of repose and compression tests. The data includes coefficients for wheat-wheat and wheat-white cast iron contacts, fracture energy distribution, and a cumulative damage coefficient. It was authored by Huapo Jia and last updated on April 13, 2026.

Use Cases

• Calibrating discrete element models for wheat grain behavior based on the provided contact coefficients.
• Simulating wheat grain fracture under compression based on the log-normal fracture energy distribution.
• Validating simulation accuracy for angle of repose tests using the provided experimental and simulated values.
• Optimizing wheat roller milling processes using the Tavares crushing model parameters.

Strengths

• Parameters are quantitatively validated with a 1.05% deviation in simulated vs. experimental angle of repose.
• Fracture force and fracture energy from the model show low relative errors of 4.47% and 1.27% respectively.
• Specific numerical coefficients are provided for elastic restitution, static friction, and rolling friction.

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 at 5.5 KB, indicating limited scope.
