Abstract

fetched live from OpenAlex

This paper presents a numerical technique to simulate the resilient modulus test of aggregate materials based on the discrete element method. This technique enables a realistic modeling that takes into account the nature of the materials and loading conditions, and provides valuable information such as the grain rearrangement at the micro level. Numerical simulations were conducted to idealize the cyclic loading of compacted granular samples. These simulations showed that the discrete element method is capable of reproducing the results of the resilient modulus test and capturing the effect of confining pressure on the resilient modulus observed in actual laboratory testing. The resilient modulus exhibited an increase in value with the increase of the confining pressure. The results also showed that the deviator stress has an effect only at low confining pressures.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
