Our last meeting was held on 6 December 2023 in Troy, MI.
The North American Deep Drawing Research Group is pleased to announce their Annual Spring Meeting on Wednesday May 1 in Troy, Michigan. Autoform USA will host the event at the PNC Building (755 W. Big Beaver Road, Troy, MI).
Breakfast and lunch will be provided. Breakfast will be available starting at 7:30am, and the meeting will start at 8:15am.
Presentations are invited covering recent work on advanced sheet metal alloys related to formability, fracture, sheared edge formability, bendability, lubrication, press technology, forming simulation, interaction between forming processes and product performance (for example, crash worthiness), and other related topics.
This meeting will have a strong focus on the topics of springback and edge cracking. Presentations on these topics are encouraged.
We invite you to make a presentation to your peers on a relevant topic – it is a great way to network with and get feedback from the best minds in the industry. Please send your name, company presentation title, and the amount of time requested for the presentation to ProgramChair@NADDRG.org as soon as possible. We have a limited number of slots remaining.
Tentative topics of presentations at this meeting include:
- Edge Stretch Performance of Outer Skin 6000 Aluminum in Typical Automotive Blanking Conditions
- The Effect That Trim Edge Quality Has on the Feasibility of Stretch-Flanging Gen3 AHSS
- A Holistic Approach to Understanding Local Formability of AHSS
- Improved DP780 hot dip coated material with balanced global and local formability for Next Gen or Complex Designs
- Simulation of shearing induced edge/interface fracture of Hot Isostatically Pressed aluminum sheets and edge stretchability of dual phase steels
- Influence of boundary condition on sheared edge fracture of a 3rd Generation 980 MPa Steel
- Sensitivity of Springback to Material and Process Parameters: A limited simulation study
- A Practical Edge Fracture Limit for Advanced High-Strength Steel
- [This list is accurate as of April 11, but may change due to last minute scheduling issues.]
