  2. 2. Co-rotational beam elements in instability problems

    Author : Jean-Marc Battini; KTH; []
    Keywords : instability; co-rotational mehtod; branch-switching; beam element; warping; plastic buckling. post-bifurcation; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The purpose of the work presented in this thesis is to implement co-rotational beam elements and branch-switching procedures in order to analyse elastic and elastoplasticinstability problems. For the 2D beam elements, the co-rotational framework is taken from Crisfield [23]. READ MORE

  3. 3. Energy-momentum conserving time-stepping algorithms for nonlinear dynamics of planar and spatial Euler-Bernoulli/Timoshenko beams

    Author : Sophy Chhang; Jean-Marc Battini; Mohammed Hjiaj; Reijo Kouhia; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear Dynamics; Energy-momentum conserving scheme; 2D co-rotational beam; Geometrically exact 3D Euler-Bernoulli beam; impact; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Large deformations of flexible beams can be described using either the co-rotational approach or the total Lagrangian formalism. The co-rotational method is an attractive approach to derive highly nonlinear beam elements because it combines accuracy with numerical efficiency. READ MORE

  4. 4. End-Shield Bridges for High-Speed Railway : Full scale dynamic testing and numerical simulations

    Author : Hesham Elgazzar; Jean-Marc Battini; Mahir √úlker-Kaustell; Morgan Johansson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed railway; end-shield bridges; structural dynamics; soil structure interaction; full scale bridge testing; controlled forced excitation; hydraulic bridge exciter; frequency response function; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : The increasing need for High-Speed Railway (HSR) to reduce the travelling time requires increasing research within this field. Bridges are main components of any railway network, including HSR networks, and the optimization of their design for this purpose would contribute to a faster and more cost effective development of the HSR network.

  5. 5. Simplified mechanical models for the nonlinear dynamic analysis of elasto-plastic steel structures impacted by a rigid body

    Author : Piseth Heng; Jean-Marc Battini; Mohammed Hjiaj; Bassam Izzuddin; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Buildings subjected to impact and explosion are usually studied using large scale and highly nonlinear finite element model which are time-consuming. The first part of the thesis deals with the development of simple and accurate models for evaluating the nonlinear inelastic behaviour of steel frame structures subjected to impact. READ MORE
