Integrated Computational Materials Engineering for Welding

Integrated Computational Materials Engineering for Welding (ICME-W)

Research activities:

  • Additive manufacturing of metals (powder bed, blown-powder, binder jetting and sintering)

  • Light-metal and dissimilar-metal joining for transportation (automotive, shipbuilding etc.)

  • Creep-resistance steels and alloys for power generation

  • Inertia and linear friction welding for aerospace engine shafts and blisks

  • Resistance spot welding, projection welding and mash seam welding of sheet metals

  • Modeling of welding and additive manufacturing processes and materials (Abaqus, Simufact, Flow-3D, DEFORM, Thermo-Calc, LS-Dyna, and Sysweld)

  • Fatigue and fracture mechanics testing and analysis of welded cast steels and dissimilar joints

  • Specialized thermal-mechanical-metallurgical testing in Gleeble with high-temperature digital image correlation (DIC) to generate "material cards" or property database for high strength steels
