Stabilized mixed formulation for phase-field computation of deviatoric fracture in elastic and poroelastic materials

In the numerical approximation of phase-field models of fracture in porous media with the finite element method, the problem of numerical locking may occur. The causes can be traced both to the hydraulic and to the mechanical properties of the material. In this work we present a mixed finite element...
