  1. 11. Structure-acoustic analysis; finite element modelling and reduction methods

    Author : Peter Davidsson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; low frequency range; building acoustics; lightweight structures; porous materials; modal reduction; substructuring; finite element analysis; structural acoustics; vibroacoustics; Structural dynamics;

    Abstract : This thesis investigates structure-acoustic systems by use of finite element analysis. The systems studied here are limited to those that consist of an enclosed acoustic fluid cavity, which is coupled to a flexible structure and/or a porous sound absorbing material domain. READ MORE

  2. 12. Biomechanical Analysis of Fall Injuries using Finite Element Modeling

    Author : Pooya Sahandifar; Svein Kleiven; Viveca Wallqvist; Yunhua Luo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fall induced injury; finite element analysis; rubberized asphalt mixture; shock-absorbing pavement; hip fracture; elderly; sideways fall; whole-body model;

    Abstract : A fall is a serious health issue for the elderly. Among different fall types, the sideways fall is considered to be more severe concerning the injury outcome. READ MORE

  3. 13. Dynamic properties of two pedestrian timber bridges : Experimental and numerical analysis at several stages of construction

    Author : Jens Bergenudd; Jean-Marc Battini; Roberto Crocetti; Patricia Hamm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic analysis; Modal analysis; Pedestrian bridge; Timber; Railings; Asphalt; Slip modulus; Finite element modelling; Dynamisk analys; Modal analys; Gång- och cykelbro; Trä; Räcken; Asfalt; Förskjutningsmodul; Finita element modellering.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Pedestrian bridges can beneficially be made from timber in order for our society to reach a sustainable future. This positive development is partly made possible due to advances in engineered wood products (e.g. glued laminated timber) and the possibilities for pre-fabrication of structural parts. READ MORE

  4. 14. Finite element methods for multiscale/multiphysics problems

    Author : Robert Söderlund; Mats Larson; Victor Ginting; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; finite element methods; variational multiscale methods; Galerkin; convergence analysis; multiphysics; a posteriori error estimation; duality; adaptivity; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Abstract : In this thesis we focus on multiscale and multiphysics problems. We derive a posteriori error estimates for a one way coupled multiphysics problem, using the dual weighted residual method. READ MORE

  5. 15. Finite Element Analysis and Design of Experiments in Engineering Design

    Author : Martin Eriksson; Innovation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element analyses; Predictive Design Analysis; Mechanical engineering design process; Design Of Experiments; Predictive Engineering;

    Abstract : Projects with the objective of introducing Finite Element Analysis (FEA) into the early phases of the design process have previously been carried out at the Department of Machine Design, see e.g. the Doctoral thesis by Burman [13]. These works clearly highlight the usefulness of introducing design analysis early in the design process. READ MORE
