Propagation of Pore Pressure and Stress in Saturated Porous Media Based on a Darcy-Brinkman Formulation

Figure 6

Normalized amplitude of pore pressure and stress versus wave travelling distance based on Darcy-Brinkman law with as a parameter (a) and with added-mass coefficient as a parameter (b) at an angular frequency of 1000 Hz. The solid line denotes the transfer function of the pore pressure, and the dash-dot line represents the transfer function of the stress. The wave travelling distance is normalized by the viscous penetration length at frequency of .
