Diffraction of Elastic Waves in Fluid-Layered Solid Interfaces by an Integral Formulation

Figure 3

Results from IBEM and DWN are shown. Spectrum of pressures by IBEM, for cases1and 2, is plotted with solid (Limestone) and dashed (pitch) lines, while those obtained by DWN are displayed using asterisk (limestone) and circle (pitch) lines. Here, good agreement between both methods is also observed.
