Abstract
By using split Hopkinson pressure bar( SHPB) device,the dynamic compression experiments of polymer bonded explosive( PBX) simulants were performed under high strain rates( 1763 ~ 2650 s- 1) loading.Sine pulse of the incident bar was obtained with a lead pulse shaper.The stress states on both ends of the specimen were monitored by polyvinylidene fluoride( PVDF) pressure sensor,respectively.The deformation and failure process of the specimen were shot by high speed camera,and the axial strain of the specimens was monitored by the laser displacement meter.Mesoscopic structure morphology and damage model of the specimen were observed by electron microscope.R esults showthat the PBX simulant is sensitivity to strain rates.C ombining with interface debonding and crystal fracture theory,the grain fracture and the separation between grain and binder are mainly mesoscopic damage model for the PBX simulant.

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.
