Transmitting Artificial Boundary of Attenuating Wave for Saturated Porous Media
Based on the constitutive equation of saturated porous media, the attenuating wave multi-transmitting artificial boundaries (AMT-ABs) for transient analysis in case of 2D and 3D are developed and its reflection coefficients are also presented. Compared with the reflection coefficient of homogeneous plane wave multi-transmitting artificial boundary (HMT-AB), the reflection coefficient of AMT-AB is the least. Via programming in APDL provided by ANSYS, AMT-AB was added into ANSYS. Numerical example is given and the analyzed results show that the AMT-AB is the most accurate artificial boundary to analyze sophisticated dynamic problems than other major local artificial boundaries.
