Abstract (en)

[origin: WO0130532A1] A method and apparatus for providing a simulation of a welding process using integrated models (100) which are interconnected by an interconnection tool (114) to determine stresses and distortions of a material being welded. The method and apparatus includes determining a model of a geometry of a set of materials to be welded, defining a set of coordinates of elements and nodes of the geometry model (102) for a finite element analysis mesh, delivering the finite element analysis mesh coordinates to a thermal analysis model (106), the thermal analysis model (106) including an analytical solution model (108) and a finite element analysis model (110), and determining a thermal analysis of the welding process, the thermal analysis responsively providing a thermal history of the welding process. The method and apparatus further includes delivering the thermal history of the welding process to a structural analysis model (112), and providing a structural analysis of the welding process as a function of the thermal history.
