Including Elastical Anisotropy Due to Texture in a Finite Element Model for the Prediction of Residual Stresses in Welds
A method is described to include welding texture in a finite element model to predict residual stresses in an austenitic weld. Due to a preferential [100] growth in the solidification direction the weld material is not elastically isotropic but transversal isotropic with the solidification direction as the fiber axis. Results show a limited difference of the predicted residual stress in the weld when considering this effect compared with a traditional model where elastically isotropic materials are used.
