Abstract

Constant amplitude and spectrum fatigue tests were performed for four large complex welded structures representing three design alternatives for window and door openings of passenger ships. Detailed stress measurements and finite element analyses were conducted. Fatigue lives for the four specimens ranged from 10(5) to 10(6) cycles. The test results showed for the,window center design with a collar plate, that the principal stress correlated best with the fatigue life and a modified design procedure was proposed. The two other designs with free edges at corners failed at welds adjacent to the corner and not directly at the corner. A discussion is given on the fatigue strength of the alternative designs and applicable fatigue design procedures.
