Undrained behaviour

WebNov 1, 2011 · The undrained soil behaviors in the post-cyclic monotonic shearing phase need further discussion, such as the strain softening, the critical strength and the development of post-cyclic pore pressure. Loading frequency is also an important issue in cyclic loading, but its effects on clay behavior are controversial. WebApr 12, 2016 · In undrained condition, the valve is closed so there is no escape path for the fluid and, so, it has to bear the load along with the skeleton. As soon as the fluid can escape through the valve, it will not take any of the construction load and all the load has to be taken by the skeleton.

WebMar 10, 2024 · Now if the soil would be undrained, this loading of the soil would just lead to excess pore pressures and not to effective stresses. Therefore we use "Ignore undrained behaviour", to make sure that when the soil weight is activated it would actually give effective stresses increase and not just excess pore pressures. With kind regards, WebUNDRAINED BEHAVIOUR Implications of undrained soil behaviour • excess pore pressures are generated • no volume change in fact small volumetric strains develop because a finite (but high) bulk modulus of water is introduced in the finite element formulation • predicted undrained shear strength depends on soil model used
