WebJul 3, 2024 · The equation that is used to calculate the total shear strength (s) of the material composing a slope, taking account of the pore-water pressure. The shear strength is then equal to the sum of the normal stress (σ) and cohesion (c). The Coulomb–Terzaghi equation is:s = c + σ. WebJan 7, 2013 · I think that equation [Cu = c*cos (phi)+p*sin (phi)] is going to give you drained strength if you apply it with phi' and p' at failure. Draw a generic Mohr circle (at failure) with its center at p' and MC envelope tangent to it. WebThe shear strength is defined in terms of effective stress parameters c’ and phi’, up to a maximum value of shear strength defined by the undrained cohesion Cu. If c’, phi’ and Cu are all constant, then you can simply enter these parameters directly in the Define Material Properties dialog. headset expander plug
