  2. 21. FEM and Scientific Visualisation as Tools in Furniture Design

    Author : Pierre Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design process; Structural mechanics; Finite Element Method; case study; furniture; conceptual design; scientific visualisation;

    Abstract : In the design process, knowledge of structural mechanics is often reduced to its use in determining whether the object that has been designed is sufficiently strong. Strength testing indicates this directly on a yes or no basis, whereas computations are able to quantify the degree of strength. READ MORE

  4. 22. Towards improved motorcycle helmet test methods for head impact protection : Using experimental and numerical methods

    Author : Shiyang Meng; Svein Kleiven; Peter Halldin; Mazdak Ghajari; KTH; []
    Keywords : Head Injuries; Helmet; Injury Prevention; Motorcycle; Test Standard; Finite Element Method; Applied Medical Technology; Tillämpad medicinsk teknik;

    Abstract : Head injury is the leading cause of death and major trauma for users of powered two-wheelers (PTWs). Helmet use can prevent and reduce head injuries when a crash is inevitable. However, today’s motorcycle helmets do not protect equally against all types of head injuries. READ MORE

  5. 23. Structural Analysis of Existing RC Bridge Deck Slabs Structural Analysis of Existing RC Bridge Deck Slabs

    Author : Jiangpeng Shu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load-carrying capacity; assessment; Reinforced concrete RC bridge deck slabs; structural behaviour; Finite element FE analyses;

    Abstract : Due to ageing of the bridge stock, continuously increasing load requirements, the need for assessing existing bridges is becoming increasingly important. Reinforced concrete (RC) bridge deck slabs are among the most critical parts to the load carrying capacity of bridges. READ MORE

  6. 24. Structural Analysis Methods for the Assessment of Reinforced Concrete Slabs

    Author : Jiangpeng Shu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge Deck; Finite Element FE Analysis; Shear and Punching; Structural Response; Reinforced Concrete Slabs; Multi-level Assessment Strategy;

    Abstract : Reinforced concrete (RC) slabs are among the most critical parts of the load-carrying capacity of such structures as bridges and parking decks. Previous research indicated that the assessment methods used in current practices largely underestimated the load-carrying capacity. READ MORE

  7. 25. Thermo-mechanical modelling of welding with experimental verification

    Author : Mats Näsström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Abstract : Residual stresses and deformations after welding were studied numerically and experimentally. The numerical simulations were performed using the finite element method. In the calculations a thermoelastoplastic material model was used. READ MORE
