STRESS CONCENTRATION IN TUBULAR JOINTS

Fatigue cracking caused by stress concentrations in tubular joints has been observed in some fixed platforms installed in hostile environments. Consequently, the ability to assess the magnitude of the stress consentration is a prerequisite to dealing with the fatigue problem of tubular joints. The problem of computing the stress concentration in three types of simple, nonreinforced joints: T-joints, K-joints and TK-joints is discussed. Semi-empirical equations are presented for estimating the stress concentration due to axial loads and bending moments.
