It seems to me that the ultimate strength of a brittle material can be easily determined by a bending test, but what about the yield? In the brittle regime, I can see how you couldn't, since the sample would fail before it would flow significantly. However, brittle materials can be made to flow a little bit by heating, confining pressure etc. In a hot bending test for example, is there a measure of the yield?
