1. 1. The Significance of Things : Affective User-Artefact Relations

   Författare :Viktor Hiort af Ornäs; Högskolan i Skövde; []
   Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; User-centred desig; User experience; Significant things; Significant use; Significant consequences; Technology; Teknik; User Centred Product Design; Användarcentrerad produktdesign;

   Sammanfattning : Products help people act, but also thrill, excite, and elicit fear, joy and anger. Artefacts are a natural part of people’s everyday lives, sometimes associated with values, dreams and aspirations. While traditional user-centred approaches have focused on efficiency and effectiveness of use, injury prevention etc. 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.

4. 3. Constitutive Behaviour and Fracture of Adhesive Layers : Inverse Methods and Energetic Balance

   Författare :Svante Alfredsson; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; constitutive behaviour; fracture; energy release rate; shear fracture; mode-mixity; experimental method; inverse solution; multi-material joints; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

   Sammanfattning : In the automobile industry, current demands on reduced emissions with maintained or even increased crash worthiness, forces the industry to seek weight-reducing designs. The possibility to use lightweight materials is obviously attractive. At joints, these lightweight materials have to be connected to high-strength or low-cost materials. LÄS MER

5. 4. Mechanical behaviour of adhesive layers : experimental methods, cohesive laws, and fracture mechanics

   Författare :Anders Biel; Kristofer Gamstedt; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental method; adhesive layer; cohesive law; fracture; fracture energy; energy release rate; peel; shear; Materials science; Teknisk materialvetenskap; Teknik; Technology;

   Sammanfattning : Adhesive joining is today viewed as one of the key technologies to achieve decreased emissions in the automobile industry. To decrease weight, optimal material selection often results in different materials for different parts. This leads to the necessity to join mixed material. Here, the use of adhesives is the most promising joining technology. LÄS MER

7. 5. Mixed mode loaded adhesive layers : from measurement of material data to analysis of structural behaviour

   Författare :Jia Li Högberg; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; mixed mode testing; cohesive law; J-integral; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

   Sammanfattning : In manufacturing of multi-material products, a joining method that is able to cost-effectively assemble components made of dissimilar and similar material, with irregular geometries, is optimal. As an alternative, adhesive bonding is in-creasingly adapted by the industry, which is also used in manufacturing of multi-phase materials. LÄS MER
