The stress-strain curve of a material illustrates its mechanical properties and gives
the forming limit beyond which it fails. Inspire Form
supports several methods for calculating the stress-strain curve.
Inputs : Sheet thickness (t), Strain hardening (n), Total elongation in 0 degree
(A80), Min Total elongation among all directions and Average
Anisotropy (r).
Method : Calculate four points to create the FLC.
Point 1: TE
No thickness dependency for the validity of the equation.
Point 2: PS
No thickness dependency for the validity of the equation.
