Penetration Characteristics of Deformable Penetrators on Steel Plates
Bibliographic record
Abstract
This study investigates the dynamic interactions between deformable penetrators and ductile metallic plates. Specifically, the analysis primarily focuses on the energy required by the penetrator under various target plate conditions. The study analyzes the energy dissipation components of this system, including the ratio of the energy dissipated by the penetrator to the energy dissipated by the plate. Furthermore, the energy dissipation within the plate is examined, including the proportions of kinetic energy and internal energy of the plate. A detailed analysis of the components constituting the internal energy of the plate is also conducted. Through this analytical study, it is observed that regardless of the plate thickness, most of the required kinetic energy of the penetrator is absorbed as the internal energy of the plate. It is observed that most of the internal energy may be attributed to the plastic deformation of the plate. Additionally, as the inclination angle of the target plate decreases below [Formula: see text], the penetration depth increases, leading to a higher dissipation of the penetrator energy, and, consequently, an increase in the required kinetic energy. These findings enable the design of target plates based on the penetrator performance characteristics.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
