Fatigue Strength and Behavior of Ship Structural Details.

Abstract

This report presents results of an experimental and analytical effort to characterize the fatigue strength of ship structural details. Test results are analyzed and compared with other data and fatigue details from various design codes. The comparisons presented allow one to determine the relative fatigue strength of different details, whether they originate from test data or design codes. The comparisons are made at low fatigue cycle levels, high fatigue cycle levels, 50 percent (mean) probability of failure and 2.3 percent (design) probability of failure. In addition to the comparisons, the fatigue strengths are ranked from weakest to strongest to allow further assessments to be made. The test data generated under this and other efforts are used to compare predicted and experimental fatigue lives where the detail was subjected to variable amplitude loadings.
