Temperature Dependent Irreversible Expression

I am working on a transient thermal model in which the temperature cycles from a lower temp to a higher temp repeatedly, with a set of temperature dependent variables.
My problem is that once the variable reaches a local maximum temperature, I would like to be able to constrain the variable so it maintains that value until a new max temp is reached.
I was thinking it is very similar to plastic deformation, or a phase change that is irreversible.
I tried to code it into the Global Expressions as:
Tmax=0+(T<Tmax)*Tmax+(T>Tmax)*T
with my variable as something like:
Var=0.5*Tmax
but I get a circular reference error.
If anyone has any suggestions, I would be grateful.
Thanks,
Matt
