1. 11. Realistic Package Opening Simulations : An Experimental Mechanics and Physics Based Approach

   Författare :Eskil Andreasson; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer; aluminium foil; semi-crystalline; progressive damage; Abaqus;

   Sammanfattning : A finite element modeling strategy targeting package opening simulations is the final goal with this work. The developed simulation model will be used to proactively predict the opening compatibility early in the development process of a new opening device and/or a new packaging material. LÄS MER

3. 12. Embodied Core Mechanics : Designing for movement-based co-located play

   Författare :Elena Márquez Segura; Annika Waern; Kristina Höök; Barry Brown; Helena Mentis; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Embodied core mechanics; embodied sketching; movement-based interaction; phenomenology; embodied interaction; play; play design; research through design; social play; co-located; movement; technology-supported; interactive toy; robot; playification; Människa-dator interaktion; Human-Computer Interaction;

   Sammanfattning : Movement-based interactive systems for play came into the spotlight over a decade ago, and were met with enthusiasm by the general public as well as the Human-Computer Interaction research community. Yet a decade of research and practice has not fully addressed the challenge of designing for the moving body and play. LÄS MER

   Sammanfattning : Mechanical Behaviour of Adhesive Layers Methods to Extract Peel and Mixed Mode Properties TOBIAS ANDERSSON Department of Applied Mechanics Chalmers University of Technology ABSTRACT This thesis is concerned with methods to extract material properties of thin adhesive layers loaded in peel and in mixed mode. The first part of the thesis is devoted to an experimental method to determine the complete stress-elongation relation (or cohesive law) for an adhesive layer loaded in peel using the DCB-specimen.

5. 14. Vibro-impact dynamics of fretting wear

   Författare :Jakob Knudsen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : The dynamics and wear of non-linear impact oscillators, comprising a single-degree of freedom system as well as continuous beam systems are analysed. The considered beams are of cantilever type with the lateral motion of the free end constrained by elastic supports. They are modelled as Bernoulli beams with Rayleigh damping. LÄS MER

7. 15. Robust design : Accounting for uncertainties in engineering

   Författare :David Lönn; Larsgunnar Nilsson; Niclas Strömberg; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust optimisation; robust design; robustness; meta model; sensitivity analysis; Solid mechanics; Fastkroppsmekanik;

   Sammanfattning : This thesis concerns optimization of structures considering various uncertainties. The overall objective is to find methods to create solutions that are optimal both in the sense of handling the typical load case and minimising the variability of the response, i.e. robust optimal designs.
