I. Janajreh et al., SAFETY INDEX APPROACH TO PREDICTING THE STORAGE LIFE OF ROCKET MOTORS, Journal of spacecraft and rockets, 31(6), 1994, pp. 1072-1078
The first-order second-moment reliability method is used to predict th
e service life of rocket motors subjected to environmental temperature
variations. All mechanical and thermal variables have statistical var
iations and correlation between variables, specifically between streng
th and modulus, as well as various distribution functions such as norm
al, lognormal, and Weibull.
