### Abstract

The rate-dependent inelastic constitutive equation was formulated by extending the subloading model such that the plastic strain rate is suppressed with the increase of strain rate and incorporating the creep strain rate in the previous article. It retains the mathematical structure of the subloading surface model and thus reduces to the model itself at infinitesimal strain rate. It belongs to the superposition model premising on the additive decomposition of the inelastic strain rate into the plastic and the creep strain rates. It is applied to metals, and its adequacy is verified comparing with various test data at a wide variety of strain rates and temperatures.
