Within the recommendations, all relevant assessment approaches, i.e., nominal, structural and notch stresses as well as fracture mechanics, are included. In addition, the relevant influ ences are covered, such as the e ff ect of post-weld treatment, mean resp. residual stresses and wall thickness. In the current update, the structure is enhanced and straightened and with it the applicability is improved. As completely new content, the assessment of welded thin joints with the notch stress approach and the impact of post-weld treatment procedures on the endurable stresses and the slope of the S-N curve is added. It is expected that the new update will have the same impact on design and other codes as the oldone. © 2023 The Authors. Published by Elsevier B.V.

1. Introduction 1. Introduction

The IIW-R ecommendations for F atigue D esignof W elded C omponents and S tructures is a worldwide used guide line to assess the fatigue strength of welds under cyclic loading. These recommendations have first been published in 1996 and updated in 2006 and 2016 [1]. They represent the state of art and science and are based on the newest experimental, methodical and numerical findings that have independently been validated. The development of the IIW-recommendations takes place the within the I nternational I nstitute of W elding (IIW). Here, the J oint W orking G roup of the Commissions XIII and XV (JWG) has the task to gather scientific results on the fatigue assessment and fatigue design of welded joints and structures.
