  2. 1. Thermomechanical behaviour of tread braked wheels

    Author : Eric Landström Voortman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical analysis; high temperature testing; thermal analysis; full-scale brake rig testing; tread braking; Railway wheels; finite element analysis;

    Abstract : Tread brakes, also known as block brakes, are a type of friction brakes commonly used in the railway industry. They are a low-cost and low-maintenance solution compared to more complicated systems such as disc brakes or electrodynamic brakes. READ MORE

  4. 2. Development and application of corotational finite elements for the analysis of steel structures in fire

    Author : Luca Possidente; Jean-Marc Battini; Nicola Tondini; Paulo Vila Real; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermomechanical finite element; Shell element; 3D beam element; Steel structures; Buckling; Fire Safety Engineering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The ignition and the propagation of a fire inside a building may lead to global or local structural collapse, especially in steel framed structures. Indeed, steel structures are particularly vulnerable to thermal attack because of a high value of steel conductivity and of the small thickness that characterise the cross-sections. READ MORE

  5. 3. Numerical simulation of thermomechanical rolling contact using an arbitrary Lagrangian-Eulerian formulation

    Author : Andreas Draganis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling contact; finite element method; thermomechanical analysis; arbitrary Lagrangian--Eulerian;

    Abstract : In the endeavour to further the understanding of thermomechanical rolling contact, numerical simulations serve as an important complement to laboratory and full-scale testing. In the development of numerical simulation methods, the challenge is to enhance predictive capabilities while keeping computational efforts reasonable. READ MORE

  6. 4. Numerical simulation of thermomechanically coupled transient rolling contact - An arbitrary Lagrangian-Eulerian approach

    Author : Andreas Draganis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical coupling; finite element method; transient analysis; arbitrary Lagrangian--Eulerian; rolling contact; frictional contact;

    Abstract : Numerical simulation of rolling contact serves as an important complement to laboratory and full-scale testing in the endeavour to further the understanding of related physical mechanisms, e.g. the influence of friction on the rolling motion, the thermomechanical interaction, damage phenomena and related modes of failure.
