Poromechanics

The continuum theory describing the coupled mechanical behaviour of a porous solid skeleton and the fluid(s) occupying its pore space, in which solid deformation, pore pressure and fluid flow are interdependent through constitutive relations, balance laws (momentum, mass) and appropriate transport laws (e.g., Darcy’s law); includes linear poroelastic formulations (Biot theory) and nonlinear extens
