  2. 1. Application of Differential Geometry to Elasticity and Corresponding Discrete Models

    Author : Nina Lautersztajn-S.; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical systems; differential geometry; isoparametric four-node elements; Lie groups; non-linear elasticity; elasticity; finite element method;

    Abstract : The amazing development in technology and industry during the last half of the twentieth century has opened totally new research fields. One of them is computational mechanics. Suddenly very complex, three-dimensional nonlinear engineering problems could be solved as a consequence of explosive advances in computers and numerical schemes. READ MORE

  4. 2. Non-linear behavior of bio-based composite : characterization and modeling

    Author : Liva Rozite; Markus Stommel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : The development and application of bio-based composite materials have been frequently studied. Most of the work is done on quasi-static performance of these materials. However, these composites are highly non-linear therefore there is need for investigation of their viscelastic and viscoplastic behavior. READ MORE

  5. 3. Empirical studies of financial asset returns

    Author : Sonnie Karlsson; Lunds universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Asset pricing; Riskaversion; Consumption; Capital investments; Multi-moment; Non-linear; International capital markets; Credit risk; Swap spread; Liquidity;

    Abstract : This dissertation aims at understanding differences in rates of returns on financial assets, both in the cross-section and over time. It contains four chapters. The first paper is "Non-separable preferences and risk aversion: Results from the UK". READ MORE

  6. 4. 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

  7. 5. Acoustical experiments on the non-linear and non-equilibrium behavior of rocks

    Author : Babak Khodabandeloo; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The study of dynamic behavior of non-perfect materials, such as rocks, is a rich topic for developing sensitive material evaluation and damage detection techniques. It has extensive applications in a variety of fields such as Physics, Geology, and Aerospace, Mechanical, Civil, Petroleum, and Material Engineering. READ MORE
