Academic Ceremony 2021

8th of October was the Academic Ceremony at BTH with promotion of PhD’s and installation of professors among other things on the agenda. From Product Development Research Lab and the research subject of Mechanical Engineering we were very happy to see the installation of two new professors in Marco Bertoni, and Sophie Hallstedt. We also […]

Introductory study of sheet metal forming simulations to evaluate process robustness

ABSTRACT The ability to control quality of a part is gaining increased importance with desires to achieve zero-defect manufacturing. Two significant factors affecting process robustness in production of deep drawn automotive parts are variations in material properties of the blanks and the tribology conditions of the process. It is imperative to understand how these factors […]

Experiments and FE-simulations of stretch flanging of DP-steels with different shear cut edge quality

ABSTRACT Dual-Phase (DP) steels are today used in the automotive industry due to its large strength to weight ratio. However, the high strength of DP-steel does have a negative impact on the general formability in sheet metal forming. Unfavourable process conditions in the press shop will, on top of this, reduce the formability of DP-steels […]

Framework for Simulation-Driven Design of Stamping Dies Considering Elastic Die and Press Deformations

ABSTRACT Sheet metal forming (SMF) simulations are used extensively throughout the development phase of industrial stamping dies. In these SMF simulations, the die and press are normally considered as rigid. Previous research has however shown that elastic deformation in these parts has a significant negative impact on process performance. This paper demonstrates methods for counteracting […]
