www.iowadot.govundisturbed samples. Typically, the total internal friction angle (ϕ) is negligible and assumed to be zero (ϕ = 0) in cohesive materials. However, if required for the analyses, the undrained (total) friction angle (ϕ) and cohesion components of the shear strength can be determined using appropriate laboratory testing methods.
