WebAug 29, 2024 · Deviatoric stress, q, is the shear or distortional stress or stress difference on a body. p and q are called s tress invariants and do not depend on the axis system chosen. p = mean stress = (σ 1 + σ 3 )/2. q = deviator stress = (σ 1 – σ 3 )/2. If q is considered in terms of effective stress; (σ’ 1 – σ’ 3 )/2 = [ (σ 1 – u ... WebThe 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 ...
