摘要：

Low-cycle fatigue behavior of modern very high strength and ultra-high strength steels with nominal strengths up to 1100 N/mm2 in welded condition is described and the application limit of elastic design rules is defined. Design recommendations are given based on the nominal stress approach as well as the notch stress approach. Thus, welded details made of high-strength steels can be designed for low-cycle fatigue applications. Furthermore, a more accurate assessment can be done, allowing for an economical application of high-strength fine-grain structural steels. 2019 The Authors. Published by Elsevier B.V.
