    PLAXIS 2D Tutorial 14: Dynamic analysis of a generator on an elastic foundation

    Application PLAXIS 2D
    Version PLAXIS 2D
    Date created 20 May 2017

    Using PLAXIS, it is possible to simulate soil-structure interaction. Here the influence of a vibrating source on its surrounding soil is studied. Due to the three dimensional nature of the problem, an axisymmetric model is used. The physical damping due to the viscous effects is taken into consideration via the Rayleigh damping. Also, due to axisymmetry 'geometric damping' can be significant in attenuating the vibration. The modelling of the boundaries is one of the key points. In order to avoid spurious wave reflections at the model boundaries (which do not exist in reality), special conditions have to be applied in order to absorb waves reaching the boundaries.

    This exercise requires a PLAXIS 2D Ultimate license to access the Dynamics features.

    The attached *.p2dxlog file contains all the commands to generate the model. With a Bentley Geotechnical SELECT Entitlement [GSE] licence, you can use the commands runner to open the *.p2dxlog file and to execute all commands in one go, see also this instruction.
