In this study, cyclic triaxial tests were performed on Zipingpu gravel, and they were followed
by a discrete element study that was designed to investigate the stress-dilatancy relationship …

A new damage-plasticity constitutive model which takes account of the effect of confining
pressure and strain rate on the strength and post-peak behaviour is proposed for rock …

A simple single bounding surface constitutive model is developed to predict the undrained
behaviours of saturated clays under cyclic loads. The new model does not involve complex …

Strain localization has been the subject of extensive theoretical and numerical studies over
the last four decades. The static and dynamic strain localization in both dry and water …

Due to the 2011 off the Pacific Coast of Tohoku Earthquake, which had a magnitude of 9.0,
many soil-made infrastructures, such as river dikes, road embankments, railway foundations …

A viscoplastic model is presented for creep and strain rate behavior of soils with particular
reference to capturing drained, undrained, primary, and tertiary creep. The model is …

A distinct feature of overconsolidated (OC) clays is that their dilatancy behavior is dependent
on the degree of overconsolidation. Typically, a heavily OC clay shows volume expansion …

Rate-dependent behavior prediction of soils under non-monotonic complex loading paths
necessitates considering more elaborated mathematical formulations. In this study, an …

Soils in the field are often subjected to time-dependent compression, where the induced
shear strength and deformation could be different upon different loading rates. To capture …

A constitutive framework for the simulation of the time-dependent behaviour of soft structured
clays has been developed from the combination of a number of existing modelling …
