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!

The NADDRG 2022 Spring Symposium will be held IN PERSON on May 19, 2022,  at the Inn at St. John’s in Plymouth, MI (44045 Five Mile Rd, Plymouth MI 48170).   Breakfast will be available starting at 7:30am, and the meeting will start at 8:30am.
