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

Figure 4

Spectrum of pressures by IBEM for cases3to6is shown. Cases3and4are plotted with dotted (granite) and circle (sandstone) lines, respectively. Moreover, in (a) case5, sandstone-granite layered model forℎ=0.05 m (solid line) and forℎ=0.10 m (dashed line) is plotted, and (b) case6, granite-sandstone layered model forℎ=0.05 m (solid line) and forℎ=0.10 m (dashed line) is displayed.
