The present study proposes a partitioned coupling framework for the implementation of a combined kinematic hardening plasticity and creep model. In the present framework, plastic and creep implicit stress integrations are performed alternately and iteratively until convergence in a partitioned coupling manner. This approach enables us to tractably implement a constitutive model that combines a plasticity model and a creep model in the program. The present framework was applied to the combination of the Ohno–Wang plasticity model and the Norton–Bailey creep model for numerical examples. The numerical examples demonstrated the capability of the present framework in analyzing realistic structures at high temperature with the consideration of both plasticity and creep.
