yield stress
Noun
Meaning
yield stress (plural yield stresses)
Synonym of yield strength
Examples
E.G. granite can flow plastically with a negligible yield stress at room temperatures, (i.e. a viscous flow).
In this case the yield stress of the steel governs the design.
The term plastic solid is often used when this plasticity threshold is rather high, while yield stress fluid is used when the threshold stress is rather low.
