Wheat Grain Fracture Model Calibration Data for Discrete Element Simulation

151.7 KB of experimental data from Huapo Jia, uploaded to figshare in April 2026, supports the calibration of a wheat grain crushing model. The data includes calibrated contact parameters for wheat-wheat and wheat-cast iron interactions, such as an elastic restitution coefficient of 0.399 and a static friction coefficient of 0.426. It also provides fracture energy distribution parameters, like a median value of 2069.78 J/kg and a cumulative damage coefficient of 5, validated against physical experiments.

Use Cases

• Calibrating discrete element method (DEM) simulation parameters for wheat grain fracture based on the provided contact and crushing coefficients.
• Validating numerical models of anisotropic grain behavior using the experimentally derived fracture energy distribution.
• Optimizing wheat roller milling processes by simulating compression and fracture with the Tavares model parameters.
• Comparing simulated and experimental force-displacement curves for grain crushing to assess model accuracy.

Strengths

• Provides specific, calibrated numerical parameters, including friction coefficients and fracture energy values.
• Model validation is described with quantitative error metrics, such as a 1.05% deviation in angle of repose and 4.47% error in fracture force.
• Data is openly licensed under CC-BY-4.0, facilitating reuse and verification.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The 151.7 KB file size suggests a limited scope, likely containing summary calibration data rather than extensive raw experimental records.
• Description metadata is limited; actual data structure and content require manual inspection after download.
