The EWI Forming Center is pleased to host two special learning opportunities this fall in advanced sheet metal forming. The programs are open to the public and will both take place in Columbus, Ohio. Fundamentals & Applications of Sheet Metal Forming ClassOctober 18-19, 2022 at EWI HeadquartersGet a comprehensive overview of sheet metal forming practices,...

Laser-welded blanks offer many advantages in automotive closures and structures, but base-material necking and cracking can be an issue. To provide better data for FE simulation modeling, EWI has developed a “mini-dogbone” tensile test for LWB formability evaluation. Hyunok Kim, EWI Forming Center Director, describes this work in Evaluating Laser-welded Blank Formability and Predicting Potential...

The increasing use of AHSS and aluminum alloys for lightweighting automotive structure necessitates a highly accurate prediction model for springback. Recently, EWI devised a cyclic tension-compression test method to qualify a new prediction model. This work is described in Cyclic Tension-compression Testing for Kinematic Hardening Material Models written by EWI Applications Engineer Laura Zoller. You...
