BTH Professors Göran Broman, Karl-Henrik Robèrt and Tobias Larsson, has together with Terrence J. Collins (Carnegie Mellon University), George Basile (Arizona State University), Rupert J. Baumgartner (University of Graz), Tobias Larsson, Donald Huisingh (University of Tennessee) been editors for a Special Issue of Journal of Cleaner Production. Now the issue is out. Find the Special […]
Read MoreABSTRACT In this work, a packaging laminate consisting of LDPE (Low Density Polyethylene), Al-foil (Aluminum foil) is focused, and failure due to necking in substrates and interfacial delamination under loading are considered. A coupled elasto-plasticity damage and fracture constitutive model is combined. The proposed constitutive model is incorporated into the FEM code ABAQUS and utilized […]

ABSTRACT In recent times a service-dominant logic is permeating the design of complex systems. However, in spite of their appeal, initiatives such as Product Service Systems (PSS) have not become mainstream, and methods are lacking to support this transition. This paper argues that methodological guidance, as well as tools for decision support, may be found […]

ABSTRACT The aim of this research is to develop an understanding of factors that enable innovation teams to conduct agile innovation work in an industrial context. The background and reason for this research are not only that innovation is necessary for companies that want to stay in business, but also that these companies need to […]

ABSTRACT A procedure based on finite element (FE) modeling, response surface-based model updating and random vibration analysis is presented to predict the fatigue life of plastic ball grid array (PBGA) components mounted on daisy chain printed circuit board (PCB). A specially designed fixture is used to mimic the typical boundary condition of plug-in PCBs. The […]
Read MoreABSTRACT Exact solutions of a nonlinear integro-differential equation with quadratically cubic nonlinear term are found. The equation governs, in particular, stationary shock wave propagation in relaxing media. For the exponential kernel the shapes of both compression and rarefaction shocks having a finite width of the front are calculated. For media with limited “memorizing time” the […]
Read MoreABSTRACT Shear fracture toughness is an important material behavior that needs to be determined and considered in many industrial fields. At the same time, shear testing is one of the complex material testing areas where available methods are few, often need special arrangements, and most of the methods do not strictly satisfy the definition of […]

ABSTRACT Thin laminates of Aluminum (Al) foil and Low Density Polyethylene (LDPE) film are essential constituents of food packages where these two substrates are bonded together with a thin layer of LDPE acting as adhesive. Noticeably, Al is a low ductile/quasi brittle material, whereas LDPE is highly ductile. The mechanism of delamination and strength of […]

ABSTRACT This paper analyzes the adoption of Additive Manufacturing (AM) technologies in Sweden. The dataset consists of a recent and representative sample of Swedish AM users (companies, universities, and research institutes). The authors investigate two questions. Firstly, what are the current applications of AM in Sweden (e.g. Rapid Prototyping (RP), production)? Secondly, what are the […]
Read MoreABSTRACT Inverse problems of nonlinear acoustics have important applied significance. On the one hand, they are necessary for nonlinear diagnostics of media, materials, manufactured articles, building units, and biological and geological structures. On the other hand, they are needed for creating devices that ensure optimal action of acoustic radiation on a target. However, despite the […]
