The most common form to express the flow curve is:σ=KεnHere σ=stress, ε=strain, n=strain hardening exponent, and K is defined as stress when ε = _______
If the specimen is deformed plastically beyond the yield stress in one direction, e.g., tension and then after unloading it is loaded in the opposite direction, e.g., compression, it is found that the yield stress is less than the original yield stress. This dependence of yield stress on direction loading is called ____________
In the stress-strain curve, loading and unloading of the material in the plastic region follow the same path.
In the stress-strain curve, loading and unloading of the material in the elastic region follow the same path.
The following flow curve shows the deformation behavior of the material in the plastic region. The material is deformed till ε1 and released; the material immediately reached to strain ε2. And the time strain reached to ε3. So, there is a delayed recovery of strain. This is behavior of material is called _________
