Simulation of fatigue crack growth in welded joints.
4th Symposium on Structural Durability in Darmstadt. Darmstadt (14.-15.5.2014)
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
This paper gives an overview on recent research results of the Darmstadt group inside a project called IBESS. Purpose of this project is the fracture mechanics based simulation of Wöhler-curves (S-N-curves) of welded joints. Part of this project is the investigation of initial defects and imperfections of welded joints. Metallographic and fractographic investigations have been done to derive a definition of an initial crack situation. --- SzM --- Another part of IBESS gives attention to the stability of the residual stress field in a welded joint due to the transient plastic deformation behaviour under cyclic loading. Numerical simulations using Döring’s material model have been done to investigate the effect of a cyclic loading on a residual stress field in an uncracked and a cracked situation.
