The soil skeleton structure (structure, overconsolidation, and anisotropy) increases and decreases as the plastic deformation varies. Previously, only the structure has been considered to be degraded; however, observation of the undrained cyclic shear behavior of medium dense sand shows that not only does the structure degrade, but a structure upgradation process also occurs. Therefore, the concept of structure upgradation accompanying plastic swelling was introduced into the SYS Cam-clay model based on the results of testing. This structure upgradation concept makes it possible to describe the cyclic mobility of sand and to explain the high ductility behavior seen in soft natural clay.
