摘要: Abstract In this study, a root-finding absorbing boundary condition (RFABC) for wave-propagation problems in infinite poroelastic media is developed. order to express the terms of local temporal operators time domain, with permeability are assumed and dynamic motions described using four scalar potentials two dilatational rotational waves. The can be expressed three independent non-dispersive P1, P2, S existing approach an RFABC waves then applied each wave component desired derived. accuracy stability developed verified at continuous level. Its discretized version formulated finite-element discrete level proved. proposed numerical waveguide. It demonstrated that produce accurate stable results finite as well permeability.
