ABSTRACT Eliciting specific intentions and seeking inspiration are important activities in the process of shaping a product’s visual appearance. A survey of the professional industrial designers was conducted to identify intentions (e.g. attributes, emotions) that they attempt to elicit, and also to identify inspiration sources and their media that they prefer not only in generating […]

ABSTRACT The fracture mechanics properties of injection-moulded low-density polyethylene (LDPE) sheets were investigated both experimentally and numerically. The total work of fracture was determined experimentally, by means of fracture mechanics testing of sheets of injection-moulded LDPE with side cracks of different lengths. A multi-specimen method, proposed by Kim and Joe (1987), was employed. The total […]

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 […]

ABSTRACT This research suggests a conceptual process of how to create high-performing innovation teams to meet the market’s need of faster ways of conducting innovation work. The CIT-process (Creating high-performing Innovation Teams) is a five-step-process systematically developed to meet organizational-, team-, and individual perspectives. On a holistic level, this research contributes to prior research by […]
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 […]
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 […]

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 […]
