Every penny spent by consumers, in countless daily transactions, acts like a vote in a continual ballot, determining how much of each and every good should be produced and drawing production to where it is most urgently required.
Once the yield criterion is satisfied, we can no longer expect to use the equations of elasticity. As shown later in this article, at the onset of yielding, the magnitude of the shear yield stress in pure shear is v3times lower than the tensile yield stress in the case of simple tension.
