Servo Press Force and Energy Considerations When Working With AHSS

Advanced High-Strength Steel (AHSS) products have significantly different forming characteristics and these challenge conventional mechanical and hydraulic presses. Some examples include the...

A New Global Formability Diagram

Bubble chart. Banana diagram. Steel strength ductility diagram—it’s been called a lot of things over the years. But the 2017 chart shown in Figure 1 is the subject of hundreds of requests for use we...

Additive Manufacturing

Additive Manufacturing (AM) has been associated with the future of manufacturing since its inception. While it does hold several advantages in complex geometries and low-volume production, modern AM...
Modelling RSW of AHSS

Modelling RSW of AHSS

Modelling resistance spot welding can help to understand the process and drive innovation by asking the right questions and giving new viewpoints outside of limited experimental trials. The models can calculate industrial-scale automotive assemblies and allow...

Roll Forming

Roll Forming

Roll Forming takes a flat sheet or strip and feeds it longitudinally through a mill containing several successive paired roller dies, each of which incrementally bend the strip into the desired final shape. The incremental approach can minimize strain localization and...
