Thermo-Rheologically Simple Material

[illiniag]

If I describe a material as a thermo-rheologically simple material, what does it mean and what are the implications of this assumption?

 

I am only guessing, but I think the statement means something which is thermo-stable interms of its rheological properities, i.e. it is a newtonian fluid, or hookean solid, or simply somewhere in between (visco-elastic i.e. gel) over a large thermal gradient. Some materials undergo a transition from one to the other upon thermal variations, and thus are complex.<br><br>
