Noun
yield stress (plural yield stresses)
Synonym of yield strength
E.G. granite can flow plastically with a negligible yield stress at room temperatures, (i.e. a viscous flow). Source: Internet
In this case the yield stress of the steel governs the design. Source: Internet
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. Source: Internet
