Finite Element Analysis of Porous Media
The equations governing the mechanics of porous media have been presented in Chap. 6. The general formulations (i.e., the full formulation presented in Sect. 6.2.4) were specialized to obtain two specific formulations: (a) The u–u–p formulation (Sect. 6.3.4) and (b) the u–p formulation (Sect. 6.4.2). In the present chapter, the weak forms and finite element equations are developed for the u–p formulation. The finite element equations for the full and u–u–p formulations may be obtained by following a procedure similar to that in this chapter (see Problem 7.1 for the u–u–p formulation).
