Fatigue strength of steel and aluminium welded joints based on generalised stress intensity factors and local strain energy values
Paolo Livieri,Paolo Lazzarin +1 more
TL;DR: In this article, the weld toe region is modelled as a sharp, zero radius, V-shaped notch and the intensity of asymptotic stress distributions obeying Williams' solution are quantified by means of the Notch Stress Intensity Factors (NSIFs).

Fatigue cracks in longitudinal ribs of steel orthotropic deck
TL;DR: In this paper, a number of fatigue cracks were found in many butt welds in the longitudinal ribs of the orthotropic deck of the Kinuura Bridge (Japan) in June 2003.

Modified Wöhler curve method, theory of critical distances and Eurocode 3: A novel engineering procedure to predict the lifetime of steel welded joints subjected to both uniaxial and multiaxial fatigue loading
TL;DR: In this paper, an approach based on the modified Wohler curve method (MWCM) applied along with the theory of critical distances (TCD) was proposed for assessing steel welded joints by post-processing simple linear-elastic finite element models.

A mathematical model to predict impact toughness of pulsed-current gas tungsten arc-welded titanium alloy
TL;DR: In this article, a mathematical model has been developed with the response surface method (RSM) to predict impact toughness of pulsed-current gas tungsten arc-welded titanium alloy weldments.

The Peak Stress Method for Fatigue Strength Assessment of welded joints with weld toe or weld root failures
TL;DR: In this paper, an expression linking the peak stress and the local strain energy value is presented, which can be used in plane problems when Mode II stress fields are non singular (at the weld toe) or of low intensity ( at the weld root), by so doing, a single design scatter band valid for either weld root failures or weld toe failures can be calibrated in terms of elastic peak stress evaluated at the critical point.
