Experimental and Numerical Analysis of Shear Process of a High Particle Content Bonding Material
Bibliographic record
Abstract
Abstract In this study, polymer-bonded sugar (PBS) is used as a substitute material for polymer-bonded explosive (PBX), and the shear failure process of PBS under compressive loading. First, the shear failure process of PBS was analyzed by a series of experiments, and it was found that the shear band appearing on the surface of the specimen was not symmetrical. Further theory analysis showed that it was triggered by the evolution of asymmetric damage caused by internal defects in the material. In addition, through investigating the distribution of experimental scatters, we found that the material undergoes a relatively long period of internal microstructure adjustment before shear failure occurs, this adjustment will undoubtedly affect the evolution of the shear band. More importantly, a data density method was used to quantify the adjustment process. Finally, by using finite element simulation, the effects of matrix–particle interface strength on the mechanical response or damage evolution of the PBS were thoroughly examined. This research has reference significance for understanding the damage evolution process of high particle content composite materials.

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.
