Abstract
The statistical techniques used in classical sensitivity testing are not directly applicable to the problem of determining the critical penetration velocity of a projectile in an armour plate. In the classical tests, the stimulus is a variable whose experimental values can be precisely controlled, but in penetration testing the impact velocity is a random variable. Six tests, which have been adapted for this specific problem, have been studied on a computer using Monte Carlo simulation procedures. One test has been found to be more accurate and economical than the others. The criterion of comparison was the root mean square error of the critical velocity obtained from a certain number of firings.
