Tag: Impedance approach Sample 1D SSI problem as an example of different approaches to SSI analysis

Let us consider 1D P-waves in a homogeneous massive rod, modeling soil. The only coordinate is x. Wave displacements u(x,t) are described by the wave equation Here с is wave velocity. In the frequency domain for certain frequency ω there exist two solutions of (11): The first wave u1 described by (12) goes up along Ох, the second wave u2 goes down.
