Example for plane stress in geotechnical
WebWe know total stress at any point within a soil mass can be written as this: total stress (σ) = effective stress (σ’) + pore water pressure (u) σ = σ' + u. from this we can write expression for effective stress: σ’ = σ – u. This relationship was proposed by Terzaghi in 1936. WebIf a circle is drawn with X as the center and XM as the radius it will be referred to as the Mohr's circle. Point M represents the stresses on the horizontal plane. So, if a line is drawn from this point which is parallel to …
