Webwhere a is the total stress and u is the pore pres-sure. The shear strength can be expressed consis-tently in terms of effective stress: s=c'+a'tan4)'=c'+(a—u)tan4)' (12.4) where c' and 4)' are the strength parameters for effective stress. For a partially saturated soil, the shear strength can be expressed as (Fredlundet al. 1978) WebJun 16, 2024 · Yield stress refers to the minimum stress at which a material will deform without significant increase in load. In other words, the minimum stress required to make a material flow is the yield stress, and it is a measure of the strength of the material structure. The stress at which yield occurs is dependent on both the rate of deformation ...
