This is the second post (here’s the first one) about an approach to introducing the derivative to calculus students that is counter to what I’ve seen in textbooks and other traditional treatments of ...
the strain-hardening is isotropic and linear. First, the flow law at a "corner" of the yield function is investigated in detail. Next, it is shown that the flow law at all points can be piecewise ...
