报告摘要：

     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.

This talk gives discusses the mechanics of porous materials infiltrated with a fluid (poromechanics), with a focus on its linear theory (poroelasticity). The theory is explained from an intuitive, phenomenological approach at the bulk continuum level, although the derivation is based on a thermodynamic variational energy approach at the micromechanical level. 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.
