    Time Domain Implementation of Transmitting Boundaries in ABAQUS for Discrete Soil-structure Interaction Systems by J. Rama Raju Patchamatla, P. K. Emani

    Published 2020-06-01
    “…Most challenging aspect of seismic SSI analysis is to implement transmitting boundaries that absorb the artificial reflections of stress waves at the truncated interface of the finite and infinite domains, while allowing the seismic waves to enter the finite domain. In this paper, the time domain implementation of seismic analysis of a soil-structure system is presented using classical discrete models of structure and interactive force boundary conditions for soil. …”

    Experimental Studies Of Electrokinetic Conversions In A Fluid-Saturated Porous Medium by Zhu, Zhenya, Toksoz, M. Nafi

    Published 2012
    “…The electrokinetic effect in a fluid-saturated porous rock is defined as the coupling and conversion between seismic and electric energies. When seismic waves propagate through a fluid-saturated formation and cause a pore fluid-flow relative to the solid matrix, the motion of the cations in the fluid- flow forms a streaming electrical current and induces an electromagnetic wave at any discontinuous interface of the formation or stationary electric potential inside the homogeneous formation. …”
