报告摘要:

In this talk, we propose an accurate hyper-singular boundary integral equation method for dynamic poro-elastic problems with Neumann boundary condition in two and three dimensions. The lecture consists of two aspects: the presentation of new regularized formulations of the strongly-singular and hyper-singular boundary integral operators, and the proposal of a novel low-GMRES-iteration regularized boundary integral equation based on an analytical preconditioner. Then their application to design fast algorithms solving the poro-elastic scattering problems will be discussed. This is a joint work with Prof. Tao Yin and Mr. Lu Zhang.
