Undrained cyclic behaviour of Beaufort Sea silt
Cyclic loading behaviour of Beaufort Sea silt has been studied under triaxial conditions, with and without static shear stress, to define the resistance to liquefaction or cyclic straining under various cyclic stress conditions. Unsymmetrical cyclic loading led to compressive failure, in which the m...
