... positive under certain conditions for the Morgenstern–Price model, but are almost always positive for the Janbu model. These findings indicate that the differential equations exhibit numerical instability, which is particularly significant near points of indeterminacy, and that the Morgenstern–Price model...

... of instability of loose sand but also affects the deformation development thereafter. Drained instability can be triggered more easily in loose sand mixed with silica fines compared with the sand on its own. At the same quantity of fines, instability can be triggered more easily for sand mixed with rounded fines...
