Modeling Abrasive Wear of Homogeneous and Heterogeneous Materials
Bibliographic record
Abstract
A micro-scale dynamic approach was recently proposed to simulate wear of materials. The model was developed based on fundamental physical laws without employing empirical equations or tribological rules. In this model, a material system is discretized and represented using a discrete lattice. Each lattice site represents a small volume of the material. During wear, a lattice site may move under the influence of external force and the interaction between the site and its adjacent sites, which depends on the mechanical properties of the material, such as the elastic modulus, yield strength and work-hardening. The movement and trajectory of lattice sites during wear were determined using Newton's law of motion. A bond can be broken when the total accumulated plastic strain exceeds the fracture strain. A site or a cluster of sites is worn away if all bonds connecting the site or the cluster to its neighbors are broken. The model can provide information on the strain distribution in a contact region, consistent with finite element analysis. This model was applied to single-phase and composite materials abraded under dry sand/rubber wheel abrasion testing condition. Good agreement between the modeling and experiments was found.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
