Modellierung eines Halbraums mit sphärischem oder zylinderförmigem Hohlraum für dreidimensionale Boden-Bauwerk-Interaktion

Coupled Itm-Fem Approach for the Assessment of the Mitigation Efficiency of Finite and Infinite Open Trenches and Soft Filled Barriers

“…The systems halfspace with cylindrical or spherical indentation can be derived analogously by shifting the cavity to the halfspace surface. Further details can be found in [24].…”

Hybrid Frequency-Time Domain Method for Three-Dimensional Seismic Analyses of Nonlinear Soils

“…1, is defined in the original space (x, y, z, t) and is valid for a linear elastic isotropic and homogeneous continuum. Using the Helmholtz decomposition and a threefold Fourier transformation one obtains a system of four decoupled ordinary differential equations which can be solved with an exponential approach in the image space (k x , k y , z, ω) [4]. This approach is referred to as integral transform method (ITM).…”
