Poroelasticity

Poroelasticity describes how porous materials, like soils or biological tissues, deform when subjected to mechanical forces and how fluids within their tiny pores move in response. When the material is compressed or stretched, it changes shape, and this deformation influences fluid pressure and flow inside it. Conversely, fluid movement can alter the material's mechanical behavior. This interplay between solid deformation and fluid flow is crucial for understanding phenomena like groundwater movement, oil extraction, or tissue mechanics in the body. Poroelasticity provides a framework to analyze and predict these coupled interactions in porous structures.
