[8] An intuitive sense of the response of a saturated elastic porous medium to mechanical loading can be developed by thinking about, or experimenting with, a fluid-saturated sponge.
The static poroelasticity considers processes in which the fluid movement and solid skeleton deformation occur simultaneously and affect each other.
[2] The dynamic poroelasticity is proposed for understanding the wave propagation in both the liquid and solid phases of saturated porous materials.
This is especially necessary when the speed of the movement of the phases in the porous material is considerable, e.g., when vibration or stress waves is present.
[13] The dynamic poroelasticity was developed attributed to Biot's work on the propagation of elastic waves in fluid-saturated media.
