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 […]

New press deflection measuring methods for the creation of substitutive models for efficient die cambering

Abstract Cost and time for die tryout are significant within the car industry, and elastic deflections of dies and presses are most commonly not considered during the virtual die design and forming simulation phase. Because of this, active surfaces of stamping dies are only cambered based on previous experiences of tool types and presses. However, […]

Welcome as Adjunct Lecturer, Johan Pilthammar!

WHO ARE YOU AND WHAT IS YOUR BACKGROUND? My name is Johan Pilthammar and I live in Hällevik, Sölvesborg, with my wife and four children. I work as a research engineer at Volvo Cars in Olofström with all kinds of projects related to sheet metal forming, mostly focused on forming simulations and material. I’ve previously […]

Towards Improving Process Control in Sheet Metal Forming: A Hybrid Data- and Model-Based Approach

Abstract Ability to predict and control involved parameters and hence the outcome of sheet metal forming processes demand holistic knowledge of the product/-process parameter influences and their contribution in shaping the output product quality. Recent improvements in the ability to harvest inline production data and the capability to understand complex process behaviour through computer simulations […]

PREDICT | 2020-

The purpose of PREDICT is to achieve increased accuracy in failure predictions by developing advanced material models, calibration techniques and effective finite element simulations, which can enable unambiguous and reliable formability predictions. Specially, simulation failure predictions of phenomena such as non-linear strain paths, effect of strain rate, anisotropy and presence of edge cracks will be […]

Applied simulation and internet of things for reduced waste during sheet metal forming

Together with Volvo Cars (Olofström), Telenor Connexion and Blue Science Part as coordinator, a research and application project has been carried out within the “Test arena Blekinge” with the aim of transforming theory into practically applicable knowledge in Industry 4.0. Industrial digitalisation has been going on since the 1990s, and with the development of the […]

Tillämpad simulering och internet of things för minskat svinn vid plåtpressning

Tillsammans med Volvo Cars (Olofström), Telenor Connexion och Blue Science Part som koordinator har ett forsknings- och tillämpningsprojekt utförts inom “Test-arena Blekinge” med syfte att omvandla teori till praktisk tillämpbar kunskap inom Industri 4.0. Den industriella digitaliseringen har pågått sedan 90-talet och med senaste decenniets utveckling av “sakernas Internet” eller Internet of Things så öppnar […]
