Leonardo da Vinci is remembered in history as a “universal genius”, he was an artist, a scientist, a mathematician and an engineer. He generated a huge amount of ideas and sketches of revolutionary concepts in his days. Although, almost none of these became reality. Why was it like that? What is the reason that brilliant ideas […]

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 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 […]

“Modelldriven utveckling och beslutsstöd” heter en av BTH:s två forskningsprofiler. Temat är hur digitala modeller kan utvecklas och användas för att snabbare utveckla nästa generations produkter som passar in ett hållbart samhälle. Under tre dagar träffades forskare och företagsrepresentanter i forskningsprofilen för att diskutera resultat och lägga ut planen för de kommande 3 åren av forskning och samverkan.

Volvo CE held the Innovation Conference XPLORATION FORUM 2016 in Eskilstuna early September, effectively displaying Volvo Concept Lab. Being closely involved in the innovation model research and development, several PDRL researchers took part. The meeting brought together researchers, engineers and innovators in the VCE network in order to share, learn, inspire, and connect. A poster […]
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 […]
