ABSTRACT 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 […]

ABSTRACT Never before has the car industry been as challenging, interesting, and demanding as it is today. New and advanced techniques are being continuously introduced, which has led to increasing competition in an almost ever-expanding car market. As the pace and complexity heightens in the car market, manufacturing processes must advance at an equal speed. […]

ABSTRACT The notion of ‘value’ has become pivotal in the PSS domain, with a plethora of ‘indicators’, ‘drivers’ and ‘measurements’ proposed to guide the assessment of PSS concepts across the design process. This paper presents the results of a systematic literature review that maps existing contributions dealing with metrics for PSS value in early design. […]

ABSTRACT Literature and field study research highlight that transiting toward PSS means for many companies to either miss interesting business opportunities or to bet on the wrong solution concept. Early stage assessment activities play a crucial role in this respect, guiding the selection of a value-adding PSS while preventing commitment of resources on poor design […]

ABSTRACT Different levels of user involvement in product design range from understanding user needs to codesigning with users. Previous research shows older patients face difficulties to handle the medication packaging. Yet the participation of older patients in pharmaceutical packaging design is underexplored. The purpose of this study is to explore the role of older patients […]
Read MoreABSTRACT This qualitative case study aims at understanding when and how industrial designers, working in design consultancies, engage in activities that will influence material selection in the design process. While the extant literature presents material selection processes as a sequence of activities aimed at finding candidate materials, there is paucity of research on material criteria […]

ABSTRACT The paper presents a study run to verify the applicability of data mining algorithms as decision support in early design stages of a product development project. The paper describes a two-stage scenario providing the rationale for the application of data science in engineering design. Furthermore, it describes a demonstrator showing how data can be […]

ABSTRACT Quality Function Deployment (QFD) is a common model to frontload engineering design activities with, linking the characteristics of a product vs. the voice of the customer using linear relationships. This approximation is often claimed to be misleading when dealing with the design of complex engineering systems. The paper presents the results of experimental activities […]
Read MoreABSTRACT We study the stability of twin boundaries and slip in crystalline orthorhombic polyethylene by means of density functional theory (DFT), using a nonempirical, truly nonlocal density function, and by means of classical molecular dynamics (MD). The results show that, in accordance with experimental observations, there is a clear preference to chain slip over transverse […]

ABSTRACT Value models, in form of economical optimization functions, are often proposed to frontload engineering design activities. However, literature argues that, when qualitative data and assumptions prevail, a qualitative assessment of the ‘goodness’ of a design is preferable against a numerical (and monetary-based) encoding of preferences. This paper explores how a model-based approach can support […]
