This chapter is dedicated to the analysis of pure deformation processes in solid continua. Within the context of porous media mechanics, the generalized local momentum balance (2.100) discussed in Sect. 2.5.1 serves as the governing equation describing mechanical deformation. In fact, the specific expression of the momentum balance (2.100) defines the equilibrium conditions in porous media here, considering swelling and thermal stresses caused by the coupling of mechanical to other physical and chemical processes. The effective stress principle has been established in order to define the stress state in the solid skeleton of porous media (cf. Sect. 2.5.1). Within this context, σeff indicates the stress tensor applied to a substitute continuum representing the solid skeleton smeared over the volume of the porous medium under consideration, and being characterized by a reduced partial density compared to the material density of the solid skeleton.
