2. 1. Aerolastic simulation of wind turbine dynamics

   Author : Anders Ahlström; Anders Eriksson; Martin O. L. Hansen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; wind turbine; aeroelastic modelling; rotor aerodynamics; structural dynamics; MSC.Marc; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Abstract : The work in this thesis deals with the development of an aeroelastic simulation tool for horizontal axis wind turbine applications. Horizontal axis wind turbines can experience significant time varying aerodynamic loads, potentially causing adverse effects on structures, mechanical components, and power production. READ MORE

4. 2. Modeling of Cold Pilgering of Tubes

   Author : Yağız Azizoğlu; Lars-Erik Lindrgren; Denis Sornin; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold pilgering; finite element method; tube forming; tool elasticity; roll flattening; Material Mechanics; Materialmekanik; Steel Forming and Surface Engineering;

   Abstract : Cold pilgering is a challenging tube forming process in terms of modeling due to the complexity in kinematic of tools, friction condition and material behavior. The process development has mostly been based on simple formulas and costly full-scale tryouts. READ MORE

5. 3. Numerical simulation of shape rolling

   Author : Stanislav Riljak; Stefan Jonsson; Peter Gudmundson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire-rod rolling; finite-element method; generalized plane-strain; dislocation density; material model; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : In the first part of this thesis, the FE program MSC.Marc is applied for coupled thermomechanical simulations of wire-rod rolling. In order to predict material behaviour of an AISI 302 stainless steel at high strain rates generated during wire-rod rolling, a material model based on dislocation density is applied. READ MORE

6. 4. Surface and Inner Deformation during Shape Rolling of High Speed Steels

   Author : Kristina Nordén; Stefan Jonsson; Jan-Olov Perä; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical manufacturing engineering; Metallurgisk produktionsteknik;

   Abstract : Shape rolling is a common manufacturing process used to produce long products i.e. bars and wire. One of the problems that might occur during rolling is defect formation leading to rejection of the finished product. READ MORE

7. 5. Simulation of Stainless Steel Tube Extrusion

   Author : Sofia Hansson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extrusion; finite element method; stainless steel; physically based material model; dislocation density; Simulering av extrusion av rostfria rör; Material Mechanics;

   Abstract : The simulation of hot extrusion processes is a difficult and challenging problem in process modeling. This is due to very large deformations, high strain rates and large temperature changes during the process. READ MORE
