1. The problem statement, all variables and given/known data The question is: calculate the total amount of strain at fracture? How much of this is recoverable strain? Explain your answer 2. Relevant equations strain = (change in length)/ (initial length) 3. The attempt at a solution I'm not sure about my answer but i just simply read of the graph. material a - 3% material b - 15% but that's in percentage form, how would I get the actual strain?
