Stress strain diagram of mild steel -- gauge length made half

  1. Jun 7, 2016 #1
    All we know the usual stress strain diagram obtained from tensile test from universal testing machine. As modulus of elasticity is material property that means till proportional limit slope will not change. As it is not a force vs elongation curve that means there will be no re-scaling to be done till proportional limit. As the gauge length is made half that means average number of voids made half. Consequently it will show some variation in yield point region.

    No clue for: (i) region between proportional limit and elastic limit
    (ii) necking
    (iii) slopes between yield point - ultimate stress point - fracture point
    Why ultimate stress and fracture stress coordinate would be same even after this new gauge length?
