Substantially, the effective stress definition is conventional and related to the problem being treated. [5] Among various effective stress formulations, Terzaghi's one seems particularly appropriate, for its simplicity and as it describes with excellent approximation a wide variety of real cases.
Erg Chebbi, Morocco. The effective stress can be defined as the stress, depending on the applied tension and pore pressure , which controls the strain or strength behaviour of soil and rock (or a generic porous body) for whatever pore pressure value or, in other terms, the stress which applied over a dry porous body (i.e. at =) provides the same strain or strength behaviour which is observed ...
Considered by many to be the father of modern soil mechanics and geotechnical engineering, Terzaghi developed the principle of effective stress, and demonstrated that the shear strength of soil is controlled by effective stress. [4] Terzaghi also developed the framework for theories of bearing capacity of foundations, and the theory for ...
The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. [1] The former was based on diffusion equations in eulerian notation, whereas the latter considered the local Newton’s law for both liquid and solid phases, in which main variables, such as partial pressure, porosity, local ...
At any point above the water table, in the vadose zone, the effective stress is approximately equal to the total stress, as proven by Terzaghi's principle. Realistically, the effective stress is greater than the total stress, as the pore water pressure in these partially saturated soils is actually negative.

The process of stress management is a key factor that can lead to a happy and successful life in modern society. [citation needed] Stress management provides numerous ways to manage anxiety and maintain overall well-being. There are several models of stress management, each with distinctive explanations of mechanisms for controlling stress.
c′ is the effective cohesion. σ zD ′ is the vertical effective stress at the depth the foundation is laid. γ′ is the effective unit weight when saturated or the total unit weight when not fully saturated. B is the width or the diameter of the foundation. φ′ is the effective internal angle of friction. K pγ is obtained graphically.
