Abstract
Physical processes accompanying high velocity impact phenomena with relative velocities 1-1000 km/s attract particular attention of mechanics and physicists over the past decades [1]. This is due to the wide prevalence of these effects in present-day technology and fundamental science. For example, they occur in inertial confinement fusion demonstration experiments with multi-layer targets (breakeven), in the development of spacecraft and vehicle meteor protection, in explosive welding and strengthening, in studying the matter properties in physical experiments with superhigh pressure values of order 0.1-1000Gbar and so on. Sometimes the interaction surface turns out to be unstable and the characteristic recurring disturbances of a conic [2] or a similar shape form on it. In this paper problems of instability development on colliding surfaces for a high velocity impact are studied by numerical simulation method using mass, impulse and energy conservation laws in continuum. Using the numerical computional results the new mechanism of the instability development from the initial shape disturbances on interacting plates surfaces is suggested, in which fundamental aspects are: 1.Mass flows deflection behind a curved shock wave front; 2.The interaction of the secondary compressed and shock waves with the primary shock waves.

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.
