  2. 1. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Author : Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Abstract : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. READ MORE

  4. 2. Outsourcing strategies for wood product manufactering firms : driving forces and strategic development

    Author : Daniel Fransson; Linköpings universitet; []
    Keywords : Outsourcing; driving forces; strategic development; wood product manufacturing firms; case studies; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : In this thesis outsourcing in the wood product manufacturing sector (WPM) is studied. More specifically, the study aims to describe and analyse outsourcing strategies for firms in the WPM industries (door, floor and window). READ MORE

  5. 3. On Transfer of Work Material to Tools

    Author : Jannica Heinrichs; Staffan Jacobson; Urban Wiklund; Uppsala universitet; []
    Keywords : Tribology; Friction; Forming; Cutting; Galling; Material transfer; Tribological coatings; Surface finish; Micro mechanisms; Aluminium; Materialvetenskap; Materials Science;

    Abstract : Bulk forming and cutting are widely used to shape metals in industrial production. Bulk forming is characterized by large strains, extensive plastic deformation and large surface expansions. Cutting is characterized by high speeds, high pressures and high temperatures. READ MORE

  6. 4. Dislocation density based material model applied in FE-simulation of metal cutting

    Author : Dan Wedberg; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : Simulation based design enables rapid development of products with increased customer value in terms of accessibility, quality, productivity and profitability. However simulation of metal cutting is complex both in terms of numeric and physics. The work piece material undergoes severe deformations. READ MORE

  7. 5. Applications of hydrodynamic forces for membrane chromatography

    Author : Björn Johansson Fast; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Membrane chromatography; FRAP; Protein accumulation; Supported lipid bilayer; Microfluidics; SEEC; Diffusion; Hydrodynamic forces; Label-free;

    Abstract : Membrane proteins are proteins that reside in the cell membrane. Due to their position in the cell membrane, the barrier between the cell interior and exterior, they are vital to cell signaling. Moreover, the presence of membrane proteins in the cell's signaling pathways make membrane proteins important drug targets. READ MORE
