Abstract

fetched live from OpenAlex

In order to obtain an equivalent underwater explosion impulsive loading,the theoretical analysis is carried out for the impact of a flyer plate on a piston,which seals a conical target chamber filled with water,based on one-dimensional elastic wave propagation and a linear equation of state for water.The impact process is simulated by using AUTODYN software,and the decay times of shock waves for two pistons with different thicknesses are analyzed and compared. According to the theory and numerical simulation research,an equivalent equipment is designed,and the pressure-time curve is measured at the central point of chamber medial wall. The results show that it is feasible to obtain an equivalent underwater explosion shock waves in the laboratory through high speed impact,and the flyer speed and the piston thickness determine the peak pressure and decay time in the conical target chamber,respectively. The equivalent equipment can be used to investigate the shock response of typical structures and materials subjected to underwater explosion impulse loading.

Teacher imitation

Not 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.
