To solve this problem we will apply the concepts of strain, flow stress and average flow stress to find the required data. We will start by calculating the Strain which is the logarithmic relationship between the longitudinal change. Later we will find the flow stress through the strength coefficient, the strain and the strain-hardening exponent. Finally with the found values it will be possible to find the average flow stress,
Now the strain is calculated with the logaritmic relation of the lengths.
With this value we can calculate the flow stress,
Here,
K = Strneght coefficient
n = Strainhardening exponent of brass
Finally the average flow stress will be given under the relation:
