In the numerical evaluation of the equations (13, (15) it makes not much difference whether the external temperature TE is constant or changing and it is possible to simulate the load and temperature input that was remarked on in Figure 3 where ott) was output. The result of that simulation is shown in Figure 9. We observe qualitatively similar ott) curves as in Figure 3. And, of course, now we can also appreciate what happens inside the body as Figure 9 gives us an idea how the phase fractions change and, by their change, dictate the deformation.

Once entropy is calculated, it becomes possible to formulate a fundamental equation of state, say as internal energy or Helmholtz free energy in terms of the independent variables which must be identified on the basis of an understanding of the physics of metal plasticity. The first problem, that of indicating a reversible path, is solved by noticing that a Gedankenexperiment producing a Volterra cut or a somigliana dislocation can be thought of as a reversible process of creating in the sample, movement of it (or annihilating) being recognized that dislocations represents the the dislocations generation and basic micromechanism for plastic behavior.
