Numerical Simulation of Fatigue Crack Growth in Different Welded Joint Zones
Abstract
This paper involves the numerical analysis of fatigue behaviour of welded joints made of steel SA-387 Gr. 91, with special attention devoted to its regions, which have very different mechanical and fatigue properties. Extensive experimental research, which was performed in order to obtain the coefficients necessary for the analysis of fatigue life of structures and parts made of this steel, was used as the base for the finite element method simulation, performed in ANSYS R19.2. Due to the typical applications of steels from this group, all experiments were performed at elevated temperature of 575 °C, which corresponds to the exploitation conditions for this material. Obtained results have shown noticeable difference in fatigue crack growth resistance of different welded joint regions, as was expected from the experimental results.
