Question
A steel specimen 12mm diameter has gauge length 50mm. the steel specimen
had tested via tensile test under maximum load 66KN with elongation 7.5mm,
and the yield load of this specimen is 15KN with elongation 2.4mm. Calculate:
1- The engineering ultimate stress (ultimate tensile strength), and engineering
strain at this point.
2- The engineering stress and strain at yield point.
3- The modulus of elasticity, and the modulus of resilience.
4- The final or fracture strain of a steel specimen, if you know that the final length
of specimen after testing is 58.5mm.
5- The true stress and strain for ultimate point.
