✦ Synopsis

This article presents an elasto/viscoplastic constitutive law that accounts for the creep behaviour of soft soils, and examines the performance of an implicit time-stepping algorithm. It is demonstrated that the update of stresses on the integration point level is most eciently performed by using a scheme similar to that developed by Borja and Lee for plasticity.
