Fatigue Life of Welded Joints of AISI 347 Stainless Steel Under Thermomechanical and Variable Amplitude Loading

Abstract: The change in operation of conventional power plants — due to the increasing use of renewable energies — from a stationary to a more flexible operation, causes additional stresses to the components by a high amount of smaller load cycles. This fact results in a demand for validated new concepts to estimate fatigue life especially for welded joints which are the weak parts within the piping. Resulting from the measured stains during operation in the LCF regime, a non-linear fracture mechanics based concept was … Show more

“…Only the latest version of a model development started in the early 1990s 12,13 and was revitalized, recently. 17,19,25,31,32 However, it should be noted that the ideas used in the authors' models are not unique. Especially the models of the IWM [33][34][35][36][37] (based on Heitmann's 38,39 damage parameter Z D ) follow similar approaches and lead to comparable results.…”
