2) Large Deformation Material Properties: Consider a material with a constitutive law: 0=85+25€0.35
MPa.
a. Find the strain at necking for this material.
b. Find the ultimate tensile strength.
c. A solid bar (manufactured from this material) with an initial diameter of 6 mm is reduced to a
diameter of 4 mm. How much force is required to achieve this deformation?
d. Find the average flow stress for the operation described in part c (E₁=0 to the €2 required to
reduce the diameter from 6 mm to 4 mm).
