For a tensile test it can be shown that the percent cold work (%CW) is related to strain according to the following relationship:

 %CW=(εε+1) × 100

Using this equation, compute the percent cold work experienced by naval brass (for which the stress-strain behavior is shown in the Animated Figure 6.12) when a stress of 415 MPa (60190 psi) is applied.
