... Abstract An overview of some of recently finished fatigue projects will be given, mainly related to higher strength steels as well as thick plates. Welded joints, i.e. butt welds and longitudinal attachments, as well as thermal cut edges will be covered. One ongoing project covering low cycle...

... Abstract The low-cycle fatigue behaviour of butt welded plates made of S960QL, and S1100QL is presented in this paper. Specimens in as welded condition and post-weld treated specimens are considered as well as the influence of yield strength on the low-cycle fatigue behavior. Summarized...

... Abstract This study aims at evaluating the redistribution behavior of the residual stress in the multi-pass FCA butt weld of YP47 in an ultra large size containership under tensile cyclic loading. A H-slit type specimen was designed in order to simulate the restraint condition of the actual...

... ABSTRACT: Fatigue test series on butt welded plates, which have been carried out at the Research Center for Steel, Timber and Masonry, have been extended by low cycle fatigue tests between 10,000 to 40,000 load cycles. Different types of the butt welds, the influence of the base materials...

..., it is very necessary to study the impact toughness of weld of steel thick plate. This paper does an experimental study on the impact toughness of butt weld of 150mm thick plate at low temperature, including weld metal and heat-affect zone. The results show that the impact toughness of them reduces...
