AN INVESTIGATION INTO THE STRESS DISTRIBUTION AND FATIGUE STRENGTH OF A WELDED TUBULAR T-JOINT

The prerequisites for fatigue analysis of tubular joints are Knowledge of local stresses at critical areas and an appropriate design S/N curve. Cumulative fatigue damage can then be calculated for a given loading spectrum. This paper describes an experimental investigation of an axially loaded small-scale T-joint to measure the maximum stress concentration and compare it with formulae from the literature, to obtain constant-amplitude fatigue data for comparison with proposed design curves and to investigate the suitability of Miner's rule from the results of variable-amplitude fatigue tests.
