View the e-book now! Is the U.S. trucking industry ready for electromobility? How much progress has been made to date to address the manufacturing challenges of electric and hybrid trucks for interstate transport? What advances are on the horizon? And how can heavy vehicle manufacturers take advantage of these new innovations and technologies? These questions...

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...
