The present work addresses a new rate-dependent inelastic model, whose response is bounded between two distinct rate-independent models. Due to the specific form of evolutionary equa tion considered, a four-step return-map integration algorithm for the time-discrete model has been developed and is presented in details. Numerical simulations illustrate the features of the model and the performances of the integration scheme.

Abstract
The present work addresses a new rate-dependent inelastic model, whose response is bounded between two distinct rate-independent models. Due to the specific form of evolutionary equa tion considered, a four-step return-map integration algorithm for the time-discrete model has been developed and is presented in details. Numerical simulations illustrate the features of the model and the performances of the integration scheme.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
