Abstract
The effective stress concept for elastic porous solid filled with barotropic fluid is discussed. The saturated porous solid is considered as the immiscible mixture consisting of two physically identifiable components. The derived constitutive stress equations (in general non-linear) for each component are used to formulate the effective stress expression. In particular, the linear relation between incremental stresses and the porous solid strains in the vicinity of an initial stress state, the effective stress-strain relation and expression for the effective stress coefficient are derived.
