# Fitted data Curve!  Upper Bound of Scatter Line.
# Material was tested by members of the Fatigue Design and
# Eval. Comm. in the 1990s. Report compiled by Prof. Peter Kurath. UoI 
# Tests included Load Control R=-1, 0.1, and 0.5, and Strain Control
# Curves were created by computing the median stress-strain curve
# and then using the Neuber plot to compute life.
# This curve is extrapolated beyond 3million  reversals to failure.
#
#Stress_units= mpa
#Strain_units= strain
#Su=  171 mpa  # ave. of 23
#Sy=  110 mpa # 0.1% strain offset.
#
#The initial modulus recorded in 18 cases as 11900. mpa ave.
#From plots of the cyclic stress-strain curve it was concluded
#that the fatigue "elastic" modulus for tests is  8600mpa
#E= 8600 mpa
