摘要：The Zero Point Structural Stress (ZPSS) approach is improved to calculate the structural stress for the fatigue life assessment of tubular joints. In the ZPSS approach, the stress distribution perpendicular to the stress classification line (SCL) can be obtained directly by post-processing the finite element (FE) results. The applicability and accuracy of the approach is verified by comparing the FE results with fatigue experimental test data. High fit degree parametric equations for stress concentration factor calculation are derived based on the ZPSS approach for stress analysis of tubular T-joints in engineering. (C) 2015 Elsevier Ltd.
