  2. 16. Modelling and simulation of mechanical cutting

    Author : Vahid Kalhori; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : The commercial success of a new product is influenced by the time to market. Shorter product lead-times are of importance in a competitive market.This can be achieved only if the product development process can be realised in a relatively small time period. READ MORE

  4. 17. Multiscale Modelling of Proximal Femur Growth : Importance of Geometry and Influence of Load

    Author : Priti Yadav; Elena Gutierrez Farewik; Marco Viceconti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone tissue modeling; deformity; biomechanics; osteogenic index; poroelastic material; octahedral shear stress; hydrostatic stress; fluid velocity; octahedral shear strain; MRI; walking; jumping; sedentation; Engineering Mechanics; Teknisk mekanik;

    Abstract : Longitudinal growth of long bone occurs at growth plates by a process called endochondral ossification. Endochondral ossification is affected by both biological and mechanical factors. READ MORE

  5. 18. Thermal impact on rolling contact fatigue of railway wheels

    Author : Sara Caprioli; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway wheels; Thermomechanical finite element analysis; Frictional rolling contact; Thermal fracture; Tread braking; Rolling contact fatigue;

    Abstract : Rolling contact fatigue (RCF) is a very common and costly damage mechanism for rails and wheels. This thesis investigates the influence of combined thermal and mechanical loading on RCF of railway wheels on the basis of numerical predictions. READ MORE

  6. 19. Microstructure-based Mechanical Behaviour in Structural Analyses of Cast Components

    Author : Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Torsten Sjögren; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; Structural analysis; Mechanical behaviour; Casting process simulation; Finite element method simulation;

    Abstract : In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component.

  7. 20. Residual stresses in paperboard and the influence of drying conditions

    Author : Magnus Östlund; Sören Östlund; Douglas Coffin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper; drying; mechanical properties; residual stress; curl;

    Abstract : The drying sequence in the manufacturing process for paperboard involves evaporation of water, primarily from within the fibres. The vapour is then transported out of the web by pressure or concentration gradients. READ MORE
