Poroelasticity

This book gives a comprehensive coverage of the mechanics of porous materials infiltrated with a fluid (poromechanics), with a focus on its linear theory (poroelasticity). Porous materials can be found in nature as inanimate bodies such as sand, soil, and rock, as living bodies such as plant tissue and animal flesh, or as man-made materials. These materials can look much different in their appearances due to their origin, but the underlying physical principles governing their mechanical behaviors can be the same. The theory is presented both from an intuitive, phenomenological approach at the bulk continuum level, and a thermodynamics based variational energy approach at the micromechanical level. The physical mechanisms covered extend from the quasi-static theory of poroelasticity to poroelastodynamics, poroviscoelasticity, porothermoelasticity, and porochemoelasticity. Closed form analytical solutions are derived in details. Physical phenomena discussed include soil consolidation, land subsidence, slope stability, borehole failure, hydraulic fracturing, water wave and seabed interaction, earthquake aftershock and fluid injection induced seismicity, heat induced pore pressure spalling, seismoelectric and seismoelectromagnetic effect, and biomechanics of cartilage, bone, and blood vessel.§§
