At room temperature and short (less than years) time frames, I think an elastic (brittle-failure as appropriate) model is the most sensical. There are some indications it is viscoelastic (at a very long time scale), but this is not even 100% agreed upon. I could be wrong, but I think elastic behavior is usually observed.
I agree with you at the room temperature we can assume it is elastic how about higher temperatures? in the transient range and above it?
Let's say you have a liquid glass and it is cooled down to the environment is it viscoelastic or viscoplastic or both? Do you know any good reference on this?
