Unified Description of Viscous Behaviors of Clay and Sand with a Visco-Hypoplastic Model
摘要
Time-dependent deformations are commonly observed in geotechnical engineering. This paper presents a unified visco-hypoplastic model to describe viscous behaviors of clay and sand by introducing a new viscous flow rule. The proposed model is capable of capturing a wide range of viscous behaviors, such as isotach behavior of clay and non-isotach behavior of sand in constant rate of strain tests. Moreover, relaxation and creep tests can be simulated as long as the corresponding conditions are prescribed.
