SEISMIC WAVE INPUT STUDY ON NONLIEAR THREE-DIMENSIONAL VISCOELASTIC ARTIFICIAL BOUNDARIES

摘要：

In this paper the seismic wave motion input method on three-dimensional nonlinear viscoelastic artificial boundary was presented. Taking the assumption that the far field medium out of the computing field is viscoelastic material and the medium in the computing field is elastic-plastic material, the radiation damping of far field medium was simulated with three-dimensional nonlinear artificial viscoelastic boundary. The force applied on the artificial boundary to implement the seismic wave input can be expressed with the displacement and velocity of the input seismic wave, which makes the seismic wave easy to input.
