Wheat Grain Contact and Fracture Parameters for Discrete Element Modeling

Coefficient of restitution measurements provide calibrated contact and crushing parameters for wheat grains. The dataset includes experimentally derived coefficients for wheat-to-white-cast-iron and wheat-to-wheat contacts, as well as fracture energy distribution and cumulative damage coefficients for the Tavares crushing model. Author Huapo Jia published this data on figshare in April 2026.

Use Cases

• Calibrating discrete element models for wheat grain fracture based on the provided contact and crushing parameters.
• Simulating wheat roller milling processes based on the validated Tavares model parameters.
• Validating angle of repose simulations for granular wheat assemblies using the provided friction coefficients.
• Analyzing anisotropic fracture behavior in wheat grains based on the calibrated log-normal fracture energy distribution.

Strengths

• Parameters are validated with low error rates, including a 1.05% deviation for angle of repose and 4.47% relative error for fracture force.
• Specific numerical coefficients are provided, such as a wheat-to-white-cast-iron elastic restitution coefficient of 0.399 and a median fracture energy of 2069.78 J/kg.
• The dataset is small (15.5 KB) and in a standard XLSX format, facilitating quick inspection and use.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's scope is limited to the specific parameters for wheat grains and white cast iron, as described in the study.
