Salerno 2016: Residual stress analysis and FEM of repair-welded titanium sheets

Review of the methodology of FEA of welding by Lindgren.

Dedicated FE software for welding Sysweld.

Strain relaxation technique is commonly used to measure residual stress. There is standard by ASTM.

Weld simulation: sequentially-coupled thermo-mechanical analysis:

1. Thermal analysis to predict thermal field
2. Predicted thermal field is then used as an input in the mechanical analysis
