Performance of a Mixed Least‐Squares Finite Element Formulation With Application in Poroelasticity
A mixed least‐squares finite element method (LSFEM), previously proposed for the theory of porous media (TPM), is further investigated in this work. Finite deformation of a fully saturated, incompressible solid–fluid binary system is studied using the LSFEM. The stress and deformation of the solid phase, along with...
