Abstract
This document presents a summary of results for Phase 2 of an experimental program to determine the collapse pressures of small-scale pressure hulls (ring-stiffened cylinders) with various amounts and patterns of simulated material loss due to corrosion. Six ring-stiffened aluminium cylinders were tested in the period from November 2006 to January 2007: two undamaged specimens, one specimen with corrosion damage to the stiffeners, and three specimens with various levels of shell corrosion. Initial analysis of the experimental data suggests eccentricity due to onesided shell thinning has a strength-reducing effect that is in addition to the thinning itself. Further analysis of load-strain data will be performed and presented in a technical memorandum at a later date. An additional aluminium cylinder without stiffeners was fabricated in order to analyze a new experimental apparatus, which was recommended after the completion of Phase 1 testing [1]. The new test setup was implemented successfully, and was found to be suitable for the collapse testing of pressure hulls.
