讲座简介:
The scattering problems for elastic waves have recently received ever increasing attention in both the engineering and mathematical communities for their important applications in geophysics and seismology. In this talk we mainly discuss a spectral accurate solver for elastic scattering problems in three dimensions. In particular, we formulate the elastic problem by boundary integral equations. Through the Helmholtz decomposition, we split the elastic wave field into the compressional wave and shear wave. We apply the rotated vector spherical harmonics as the basis to discretize the coupled boundary integral equation. The well-posedness of the coupled system, as well as its applications to the multi-particle elastic scattering will also be discussed.
