The most common form to express the flow curve is: σ=Kεn Here σ=stress, ε=strain, n=strain hardening exponent, and K is defined as stress when ε = _______

The most common form to express the flow curve is: σ=Kεn Here σ=stress, ε=strain, n=strain hardening exponent, and K is defined as stress when ε = _______ Correct Answer 1

In the following flow curve substitute the value of ε=1 σ=Kεn => σ=K(1)n => σ=K So, K is defined as the value of stress when ε=1.
