1. Railway track dynamic modelling
Abstract : The railway vehicles are an increasing mean of transportation due to, its reduced impact on environment and high level of comfort provided. These reasons have contributed to settle a positive perception of railway traffic into the European society. READ MORE

2. Artificial Ground Freezingin Clayey Soils : Laboratory and Field Studies of Deformations During Thawing at the Bothnia Line
Abstract : Artificial ground freezing as a method to temporarily stabilize and create hydraulic sealing in urban as well as in rural areas has been used in a number of Swedish construction projects, particularly during the last decade. One problem with the freezing of soil and rock is that fine-grained clayey types of soils have showed a tendency to under certain circumstances, during the thawing process, create a pore water overpressure and to consolidate, despite a change in the external loading conditions.

3. On the Dynamics of Porous Media - Application to Road and Railway Structures
Abstract : Load-bearing road and railway structures normally consist of layers of particulate porous materials, often with bitumen-based binders. The layered system is subjected to dynamic loading from traffic, which inevitably causes material deterioration that enhances permanent surface deformation. READ MORE

4. Computational Modeling of the Dynamics of Fluid-Filled Porous Media with Application to Road and Railway Structures
Abstract : The dynamics of fluid-saturated porous media is a challenging topic with applications in many engineering fields like, e.g., road and railway mechanics. The complexity of the problem requires high computational effort when performing simulations of the coupled dynamic deformation and fluid flow in a saturated porous medium. READ MORE

5. Influence of thermal loading on mechanical properties of railway wheel steels
Abstract : Material integrity and properties of wheels are critical in railway traffic, as wheels fulfil the important function of transferring load and traction from the vehicle to the rail track. Steels with a pearlitic microstructure are commonly used for wheels due to their height strength, low cost and good wear properties. READ MORE
