Effect of operating conditions on the bursting performances of cross-grooved domed rupture disc
Bibliographic record
Abstract
The cross-grooved domed rupture disc (CDR) is widely used due to its rapid response and the absence of fragment spattering. The bursting performance of the CDR is primarily affected by the operating conditions including the applied pressure, clamp fillet radius, and pressure rise rate. In this study, a systematic investigation was conducted to examine the dynamic bursting pressure (DBP) of the CDR under varying operating conditions. A numerical model of the CDR was developed and validated against the dynamic bursting test results. The applied pressure conditions, including the operating pressure and back pressure, were thoroughly analyzed. The results indicate that an increase in applied pressure leads to a decrease in DBP. In certain cases, the presence of back pressure can cause premature failure. This behavior is attributed to the combined effects of residual stress and plastic deformation. Furthermore, due to shear stress at the boundary, the DBP of the CDR decreases as the clamp fillet radius increases. Finally, as the pressure rise rate increases, the DBP initially rises and then declines, which can be attributed to the strain rate effect of the material.

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.
