Abstract
AbstractA novel elastoviscoplastic model is proposed to improve the modelling of the one‐dimensional unloading response of soils. Creep is modelled as an isotache process, but with the possibility to incorporate distortion of the isotaches after unloading. Upon unloading, swelling develops as a transient superimposed process that enables the sequential occurrence of swelling and creep as observed in experiments. The model features a flexible reference isotache to improve the fit to real laboratory tests. The model is implemented with full hydro‐mechanical coupling and enables simulation of both load‐controlled and strain rate‐controlled stress paths. The model is calibrated with a laboratory test with a complex stress path including constant rate of strain, incremental loading and relaxation stages.
