2. 1. Multiphase continuum modeling of wood : A hybrid mixture theory approach

   Author : Winston Mmari; Björn Johannesson; Lynn Schreyer; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture transport; Coupled heat and moisture; Over-hygroscopic; Hybrid mixture theory; Mixture theory; Swelling; Hygro-mechanical; Non-linear elasticity; Large deformation; Phase field crack model; Anisotropic cracking; FEM; Numerical model; Norway spruce; Wood; Porous media; Forestry and Wood Technology; Skog och träteknik;

   Abstract : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. READ MORE

4. 2. Modeling of foams for impact simulations

   Author : Mats L Landervik; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Theory of Porous Media; Shell theory.; Constitutive modeling; Multiscale Analysis; Foams; Computational Homogenization;

   Abstract : Stimulated by the strong drive in the automotive industry to reduce energy consumption,and, linked to that, the need to reduce weight, this thesis concerns modeling of foams forimpact simulations. To start with, a continuum hyperelasto-viscoplastic model is developedwithin the framework of Theory of Porous Media. READ MORE

5. 3. Multiresolution Continuum Theory and Dislocation Density Based Constitutive Relations

   Author : Hao Qin; Kenneth Runesson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik; Centrumbildning - Centrum för högpresterande stål CHS ; Centre - Centre for High Performance Steel CHS ;

   Abstract : In classical description, the mechanical state of a material point depends on the variables defined at this point solely. It can integrate and catch some aspects of the material’s microstructure by conventional homogenization method. READ MORE

6. 4. Constructing Historical Realism : International Relations as Comparative History

   Author : Martin Hall; Statsvetenskapliga institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; theory; historical sociology; feudalism; Late Antiquity; Japan; Republican Rome; Political and administrative sciences; Statsvetenskap; förvaltningskunskap;

   Abstract : In this study the author seeks to develop Historical Realism as a new approach to International Relations. Drawing on recent theoretical developments in International Relations and Historical Sociology it is argued, first, that a distinction between constitutive and causal theory is necessary and, second, that this distinction makes comparisons at a high level of abstraction across time and space possible.

7. 5. On the Design and Life Prediction of Transmission Belts Made of Elastomer Composites

   Author : Dag Fritzson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Material properties; Elastomer; Composite; Damage; Fatigue; Viscoelastic; Anisotropic; Wear; Constitutive theory; Life prediciton; V-belt; Belt transmission; Rubber;

   Abstract : Next to gear transmissions, belt transmissions are the most important mechanical transmissions. Today, belt design and development is based on extensive application tests of belts in the product development process. There is a need for theory development and design support systems. READ MORE
