Abstract
The simple “composite” model of material with inhomogeneous dislocation structure is extended to provide information on strain response to stress changes in steady-state creep. This extension enables us, therefore, to simulate the so-called dip-test technique and to calculate operationally defined internal stress. It is shown that this internal stress corresponds to the back stress acting in soft regions. The model is also convenient for the calculation of strain transients.
