研究目的
To compare sequential methods, estimators, and stopping criteria used in the Department of Defense (DoD) for ballistic resistance testing to those found in literature, aiming to improve efficiency and accuracy in estimating the probability of perforation.
研究成果
The study concludes that the three-phase optimal design, a probit model, and a break separation stopping criteria are most accurate and efficient at estimating V50, while the three-phase optimal design or Robbins–Monroe–Joseph method should be used to estimate V10. It suggests improvements to current DoD protocols by employing more recent sensitivity test design methods and maximum likelihood estimation techniques.
研究不足
The study is limited by the small sample sizes typical of DoD ballistic testing, which may affect the accuracy and efficiency of the methods compared. Additionally, the inclusion of a velocity set point error introduces variability that could impact the results.
