Many geotechnical problems, such as buried pipeline–soil interaction and wave loading on
sand seabeds, require the soil behaviour at relatively low effective stresses as compared to …

Multidirectional shearing of granular soils involves shearing more than one shear stress
component, and thus may result in more-complex soil responses than unidirectional …

Multidirectional shearing tests on soils in the laboratory suffer from drawbacks such as non-
uniformity of stress and unknown horizontal stress of the specimen. As a promising …

The discrete element method (DEM) is crucial in investigating and modeling the elementary
behavior of granular materials under varying loading conditions, especially those that …

Seismic site response analysis (SSRA) is typically performed considering only one
horizontal component of earthquake excitation. In many cases, however, two or three …

In-situ soil deposits often have an initial shear stress that significantly affects their
subsequent cyclic behavior and liquefaction susceptibility. This is closely related to the …

Multidirectional cyclic shearing induced by earthquakes involves variations not only in
amplitude but also in direction. To investigate the undrained cyclic shear responses of sand …

Huge and critical structures, such as fuel storage tanks and nuclear power plants, are often
built on dense sandy grounds, which may cause excessive plastic deformations under …

Abstract A generalized Drucker–Prager (GD–P) viscoplastic yield surface model was
developed and validated for asphalt concrete. The GD–P model was formulated based on …

Bidirectional shear test provides a physical way to study the complex response of soils
subjected to cyclic shearing applied simultaneously in two directions on a plane. This test …
