Question
Problem :-
The following data was obtained tensile test on a specimen of 6 mm diameter and
gauge length Lo=30 mm:
load(KN)
0 40
80 95 90
135 150.2 145 130 120
elongation(mm) 0 0.022 0.13 0.25 0.55 2.01 3.88 4.12 5.22 6
Plot engineering and True (stress-strain) curves, then determine the (oy, ɛy), (ou,
ɛu), (of, , ef), ductility, modulus of elasticity.
Then select on the drawing ((strain hardening (n)) , (Necking), (uniform plastic
region and non-uniform plastic region) and (elastic & plastic) region)?
