Undrained behaviour
WebDec 27, 2024 · The undrained monotonic shear behavior of sand with a small amount of fines (0–20%) has been scrutinized through a series of triaxial tests. The following … WebJan 20, 2024 · The undrained shear strength is then defined by using the deviator stress mobilised at the state of phase transformation. This dilative behaviour is categorised as ‘no flow’. When the specimen is loose, it shows contractive behaviour along the points B″ and C″, where the points B″ and C″ correspond to the quasi-steady state and steady state.
