F 300 Ductile Characteristics
App.C F
301 A typical schematic of a stress-strain curve for a ductile material
is shown in Figure 3. The following elastic parameters are shown:
elastic modulus for the linear range and non-linear range (E or
G for shear), strength and strain at failure point (sult and eult), strength and strain at
yield point (syield and eyield).Guidance note:
Here the yield point is defined as the intersection between
the stress-strain curve and the 0.2% offset of the linear
relation. ---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---

for a ductile core materials.

302 For the calculation of modulus of elasticity, see C102. The linear limit is defined
here to be the same as the yield point.
