Klaus Thoeni proposed the following answer:
It should be possible if you don't change the equilibrium state. So
let's say in your first phase you are loading up to a specific strain
(or displacement). For the second phase you change only the behaviour
thereafter. You still need to replicate parts of the C++ code to assign
all relevant parameters (displForceValues, stiffnessValues). This is
because everything is initialised at the creation of an interaction and
the C++ code assumes it can not change during the simulation. Also, you
would not be able to change the number of points of the stress-strain
curve, hence start with the maximum points (it doesn't matter if they
are on one line).
