Time-history responses on the surface by regularly distributed enormous embedded cavities: Incident SH-waves

  • The time-history responses of the surface were obtained for a linear elastic half-plane including regularly distributed enormous embedded circular cavities subjected to propagating obliquely incident plane SH-waves. An advanced numerical approach named half-plane time-domain boundary element method (BEM), which only located the meshes around the cavities, was used to create the model. By establishing the modified boundary integral equation (BIE) independently for each cavity and forming the matrices, the final coupled equation was solved step-by-step in the time-domain to obtain the boundary values. The responses were developed for a half-plane with 512 cavities. The amplification patterns were also obtained to illustrate the frequency-domain responses for some cases. According to the results, the presence of enormous cavities affects the scattering and diffraction of the waves arrived to the surface. The introduced method can be recommended for geotechnical/mechanical engineers to model structures in the fields of earthquake engineering and composite materials.
