Glass behaviour-viscoelastic or viscoplastic?
Sun, 2009-06-07 23:55 - sn_sohail
I am a bit confused about glass (silicate glass) material behvoiur. If it is viscoelastic how does it deforms? Does anyone knows any good reference?
Thanks

Elastic
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.
Mike, I agree with you at
Mike,
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?
Thanks
