A time-saving tool to calculate failure behavior
The submarine's commander must have sufficient information at his disposal to take a well-considered risk as he passes his ship beyond operational depth. A designer can calculate these risks using probabilistic analysis. But since these analyses are performed with numerical simulations, they are time consuming. Nevesbu is developing a new, compact formula that can accurately portray failure behaviour in a shorter calculation time. This tool is named PHAReB (Pressure Hull Analysis on a Reliability Base). The study focuses on the application of numerical simulation using the Response Surface Method or Monte-Carlo simulation. But in contrast to the present situation, it is limited only by computer power.
