Wheat Grain Compression Simulation Parameters for the Tavares Model

A set of calibrated contact and crushing parameters for wheat grains using the Tavares crushing model. The dataset was created by Huapo Jia and published on figshare in April 2026. It contains parameters derived from physical experiments and simulation, including friction coefficients and fracture energy distribution.

Use Cases

• Calibrating discrete element method (DEM) simulations for wheat grain fracture based on the described Tavares model parameters.
• Optimizing wheat roller milling processes based on the calibrated contact parameters between wheat and white cast iron.
• Validating simulation models of anisotropic grain structures using the provided fracture energy and cumulative damage coefficient.
• Conducting numerical studies on agricultural material behavior using the systematically calibrated elastic restitution and friction coefficients.

Strengths

• Parameters are quantitatively validated with reported relative errors, such as 4.47% for fracture force and 1.27% for fracture energy.
• Specific calibrated values are provided, including an elastic restitution coefficient of 0.399 for wheat-white cast iron contact.
• The dataset is openly available under a CC-BY-4.0 license, facilitating reuse and modification.

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 (9.5 KB), indicating a limited scope focused solely on parameter values.
