ABSTRACT The aim of this study is to evaluate a new pedagogic approach implemented in a compulsory materials course for product design students at bachelors level at ABC University. When developing a new curriculum for the material course, a decision was made to teach materials and production methods in a contextualized setting with emphasis on […]

During two days some 25 people gathered at BTH campus and Product Development Research Lab to take part in session #2 of the National PhD course “Modeling Simulation and Optimization in the Engineering Product Development Process”.
Read MoreABSTRACT Sheet metal forming in the car industry is a highly competitive area. The use of digital techniques and numerical methods are therefore of high interest for reduced costs and lead times. One method for reducing the try-out phase is virtual rework of die surfaces. The virtual rework is based on Finite Element (FE) simulations […]
Read MoreABSTRACT 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 […]

Students in the course MT2545 Knowledge Enabled Engineering had today their final group project presentation at Dynapac Compaction Equipment AB. Under LP2, Mathilda Weinert, Anton Sterner, Simon Thorstensson and Mostafa Salman have worked with enterprise modelling and simulation tools to optimize the drum manufacturing process of small and large asphalt compactors. MT2545 Knowledge Enabled Engineering […]
Read MoreABSTRACT 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 […]

ABSTRACT Manufacturing organizations shall recognize sustainability as a business occasion to capitalize on, rather than an undesirable pressing situation. Still, empirical evidence shows that this opportunity is hard to capture and communicate in global strategic decisions, through planning by tactical management, to daily operational activities. This paper systematically reviews the modeling challenges at the crossroad […]

Modelling and simulation is today a natural part of engineering design in businesses of all types and sizes. However, transition from simulation as primary a tool for verifying solutions that are already decided upon towards use of simulation to stimulate creation of new concepts and provide guidance towards more optimized designs, especially in early development […]

ABSTRACT Injection-moulding is one of the most common manufacturing processes used for polymers. In many applications, the mechanical properties of the product is of great importance. Injection-moulding of thin-walled polymer products tends to leave the polymer structure in a state where the mechanical properties are anisotropic, due to alignment of polymer chains along the melt […]
Read MoreABSTRACT This work present an approach of how to account for the anisotropic mechanical material behaviour in the simulation models of the thin aluminium foil layer (≈10 μm) used in the Packaging Industry. Furthermore, the experimental results from uniaxial tensile tests are parameterised into an analytical expression and the slope of the hardening subsequently extended […]
