  1. 1. Computational Modeling of the Dynamics of Fluid-Filled Porous Media with Application to Road and Railway Structures

    Författare :Bernd Lenhof; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road; hydro-mechanical modeling; poromechanics; railway; porous media; binary phase mixture;

    Sammanfattning : 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. LÄS MER

  3. 2. On the Dynamics of Porous Media - Application to Road and Railway Structures

    Författare :Bernd Lenhof; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poromechanics; dynamics; railway; multiphasic mixture; hydro-mechanical modeling; internal erosion; road; porous media;

    Sammanfattning : 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. LÄS MER
