The finite element model WeldsimS has been developed that quantifies residual stresses in welded steel structures. Input to the model is the structure geometry, material properties, and welding procedure; the output includes the development of temperature, stress, and strain fields during the welding operation. The residual stress field is then made available for a failure assessment analysis.
All main mechanisms causing residual stresses in steel are included in WeldsimS:
Some WeldsimS features:
Temperature field during deposition of weld metal in the groove.
Residual hoop stress for 2 different levels of local mesh refinement.
