how to calculate LOG true stress vs LOG true strain
calculate strain hardening factor n If certain number values of true stress are there then we can calculate from the Graph by drawing a tangent to the the curve formed.

Number of values of stress will occur when cross sectional areas near the failure are taken a 3-5 readings
