Question
![. In a uniaxial tension test, a dog-bone-shaped specimen is pulled in a machine. During the test, the force
applied to the specimen, F, and the length of a gage section, L, are measured. The true stress, O,, and the
true strain, &,, are defined by:
0₁ =
F (KN)
L (mm)
FL
EI.
A Lo
:
&₁ = In
#
where A and Lo are the initial cross-sectional area and gage length, respectively. The true stress-strain
curve in the region beyond yielding is often modeled by:
o =KE
The following are values of F and L measured in an experiment. Use the linearized form of the above
equation determining the value of the coefficients K and m that best fit the data. The initial cross-sectional
area and gage length are 4 = 1.25.10 m² and Lo=0.0125m.
