Fatigue Strength of Lugs Containing Liners. Volume 2. Computer Program Used for Analyses

Abstract

This report presents the results of an investigation of the fatigue strength of structural lugs. The program included both experimental and analytical phases which were used in a complementary fashion to formulate design charts for fatigue-loaded steel and titanium lugs containing interference fit liners. These lugs are representative of design practice in highly loaded aircraft applications, particularly that found in helicopter blade attaching systems. A primary element in the analytical study was a two-dimensional structural analysis of lug configurations, which was done by finite-element methods using a computer program.
