Fatigue assessment of welded joint is still far from being completely solved now, since many
influencing factors coexist and some important ones should be considered in the developed …

Welding-induced residual stresses evolve under external loading and fatigue actions. This
paper examines the effects of a variety of influencing factors on the residual stress evolution …

In this work, load-controlled low-cycle fatigue tests of butt and lap joints are conducted, and
a structural strain range parameter is proposed to characterize the fatigue behavior of …

This study investigates the low-cycle fatigue (LCF) behavior of the high-strength steel S550
(commonly used in ship and floating structures) under different strain amplitudes with …

This paper proposes the framework to determine and update the crack-front profile at the toe
of welded plate joints based on the strain relaxation data. This study determines the crack …

This paper presents an enhanced neural network-bootstrap particle filtering algorithm to
construct the complex relationship between the normalized strain relaxation indicators and …

The probability of offshore platforms suffering to extreme cyclic loads, such as storm surges
and typhoons, increases highly at deep sea. It is essential to achieve the hysteresis behavior …

This work provides a post‐processing procedure to predict the high‐and low‐cycle fatigue
life of welded structures. The post‐processor calculates the equivalent structural strain …

Welded tubular joints are integral components in various engineering structures, subject to
cyclic loading conditions throughout their operational lifespan. This paper investigates the …

In this paper, local approaches are employed to analyse stress distributions, local fatigue
indicators of weld toe, and weld root in load‐carrying cruciform welded joints (LCWJs). An …
