Hi Andre,
the new terms for evaluating fading memory stresses are implemented now, check [1]. It was a little bit tricky for the 'eth' version of terms because to compute stress one needs to know whole history of loading - there is no cut-off. Therefore 'preserve_caches' argument has been introduced to ProblemDefinition.evaluate() - it must be set to True to evaluate such terms correctly.
I have also changed the loading according to your suggestion. To get the time history plots, follow the instructions at [1] (or in the example docstring).

Even better would be to remove the load after 10 steps, say, to see delayed
stress/strain recovery.

The stress/strain response of these materials are non-linear with time. I
suggest extending the example to show these responses with plots of stress
vs. time and strain vs. time. Can the de_cauchy_strain/stress terms be used
for this?
