Next Meeting

Our last meeting was held virtually on 10 and 11 June 2021. It was a success!! A list of topics from that meeting is found at the bottom of this page

The next NADDRG meeting will be held virtually on the mornings of December 2 and 3, 2021. Send a message to MeetingCoordinator [at symbol] NADDRG [dot symbol] org to register.

Tentatively, we are scheduled to hear talks on these topics at the December 2021 meeting:
  • Constitutive characterization of an 1800 MPa press hardening steel under hot stamping conditions
  • Simulation of Dynamic Effects in Progressive Die Operation and Control
  • Recent Progress on LWB formability
  • Questioning the FLD Marginal Line
  • A feasibility study of the high-speed shearing of AHSS to fabricate the laser-welded blank (LWB)
  • In-Situ Experiments to Elucidate Temperature and Strain Rate Effects on TRIP in Q&P Steels
  • ULTRA FORM® 780 AHSS Formability Characterization
  • Consistency of Artificial Ageing 6xxx Aluminum Alloys in Support of Numisheet Benchmark
  • An Experimental Methodology to Characterize the Uniaxial Fracture Strain of Sheet Metals using the Conical Hole Expansion Test
  • …and more!
