Next Meeting

Our last meeting was held virtually on 2 and 3 December 2021. It was a success!! A list of topics from that meeting is found at the bottom of this page

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 8:00am.

We have arranged for a block of discounted rooms at the Hotel. You can book with them by clicking the link here, or or call into the hotel directly at 734-414-0600.

This meeting will focus on Digital Image Correlation as applied to sheet metal forming and fracture. This meeting is co-sponsored by the North American Deep Drawing Research Group (NADDRG) and the Auto/Steel Partnership (A/SP), and covers an important range of DIC-related topics:

  • Best practices and standardization
  • Forming (necking) limit characterization
  • Fracture limits
  • Nonlinear strain paths

The meeting should be of interest to technical specialists (stamping, modeling), manufacturing and materials engineers, as well as those with less exposure looking to gain knowledge regarding this innovative technology.

Speakers and topics include:

  • Mark Iadicola – Director of the NIST Center for Automotive Lightweighting and President of the International DIC Society: “DIC Good Practices and International Standardization”
  • Dirk Mohr – Chair of Artificial Intelligence in Mechanics and Manufacturing, Institute for Virtual Manufacturing, ETH Zurich and Impact and Crashworthiness Lab, Department of Mechanical Engineering, MIT, Cambridge USA: “From Planar to Surround DIC: Increasing the Robustness of Plasticity and Fracture Model Identification”
  • Thomas Stoughton – Technical Fellow and Lu Huang – Senior Researcher, Manufacturing Systems Research Lab, General Motors Global R&D Center: “Aggressive Use of DIC Technology to Improve Simulation of Metal Deformation”
  • Cliff Butcher – Professor and Co-Director, Forming and Crash Lab, University of Waterloo: “Fracture Characterization in Simple Shear Across Lengthscales using Optical Strain Measurement”
  • Fadi Abu-Farha – President and Technical Manager, FADI-AMT: “From Standard to High Speed DIC: Investigating Rate Effects on Formability and Fracture”
  • Yannis Korkolis – Professor, Integrated Systems Engineering, Ohio State University: “Recent Applications of Digital Image Correlation in Constitutive Modeling and Formability Assessment”
  • Kaab Omer – Senior Formability Engineer, Novelis: “Implementation of Curvature Neck Detection Methods”
  • Gang Huang – Lead Research Engineer, ArcelorMittal Global R&D: “Experimental Methods for the Determination of Forming and Fracture Limits of AHSS”
  • Sergey Golovashchenko – Professor, Mechanical Engineering Department and Director, Center of Advanced Manufacturing and Materials, Oakland University: “Determining Fracture Strain in Stamping Operations: Challenges and Opportunities”
  • Hyunok Kim – Forming Center Director, EWI: “Applications of the DIC Technique for Characterizing the Formability Limit of Laser-Welded Blanks”
  • [This list is accurate as of May 1, but may change due to last minute scheduling issues.]
