42nd International Deep Drawing Research Group Conference - IDDRG 2023

The topic of this plenary lecture is “SSAB’s transformation to Fossil Free Steel with the HYBRIT Technology”.

With Luleå as the location of the conference, we will present to you the history of the press hardening process, the invention originated from Luleå. Together with the growing interest and use of the press hardening process, it came an increased need to predictand simulate the process. Something that has been developed here, and still is being further developed.

The paper will present the development of sheet metal forming simulations at Volvo Cars since the late 1980’s until today. Major breakthroughs during the development will be presented as well as the current state of the art. Finally the future challenges for the sheet metal forming community, e.g. sustainable metals, and ideas how to solve these challenges will be presented.

Special AI applications are gaining more and more importance as replacements for material models in metal forming and are used in manyareas of digital twins, such as soft sensors or predictive tools. The main advantage of AI models in this field is found by the capability of code of programming itself based on the simulated or experimental data provided, without the need for explicit...

Manufacturing Engineering Casting & Stamping within Volvo Cars is continuously evaluating, developing, and implementing new technology.
This presentation gives an overview of recent research and implementations in the area of simulations and virtual tryout of industrial dies.
Volvo Cars has also started the journey towards Smart Manufacturing & Digital Twins, an area with great potential and...

Stamping simulation are accurately representing the reality today. Various quality requirements like splits, wrinkles but also springback and surface appearance are predicted. In orderto effectively execute the tryout process the process setup of the simulation has to be reproduced. However, the try-out process can be accelerated if specific information out of the simulation has been...

An Overview of press hardening applications and an attempt to look into the crystal ball. How does press hardening meet the challenges of our time?

The modeling of material behavior for both plasticity and fracture requires the development of increasingly accurate tests. On the one hand, the development of DIC allows to revisit tests such as the bulge test or the in-plane torsion. On the other hand, recent results show the enormous value of using robotics to perform mechanical tests. The benefits are an unmatched combination of speed,...
